PART I.       FINANCIAL INFORMATION

Item 1.       Condensed Consolidated Financial Statements

        The condensed consolidated financial statements included herein have
been prepared by the Company, without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission. Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to such rules and regulations, although the Company believes
that the disclosures made are adequate to make the information presented not
misleading. It is suggested that the condensed consolidated financial statements
be read in conjunction with the consolidated financial statements and the notes
thereto for the year ended December 31, 1997 included in the Company's Annual
Report on Form 10-K.

        These financial statements have been prepared in all material respects
in conformity with the standards of accounting measurements set forth in
Accounting Principles Board Opinion No. 28, "Interim Financial Reporting," and
the rules and regulations as specified in the Securities Exchange Act of 1934
and reflect all adjustments, consisting only of normal recurring adjustments
which, in the opinion of management, are necessary to summarize fairly the
Company's consolidated financial position, the results of operations and cash
flows for the periods presented. The results of operations for such interim
periods are not necessarily indicative of the results to be expected for the
full year.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)


1.      Earnings (Loss) per Share

        In the fourth quarter of 1997, the Company adopted Statement of
Financial Accounting Standards ("SFAS") No. 128 "Earnings Per Share." Earnings
(loss) per share amounts for all previously reported periods have been restated
to conform with SFAS No. 128. Basic earnings (loss) per share is calculated
using the weighted average number of common shares outstanding during the
period. Diluted earnings (loss) per share is calculated using the weighted
average number of common shares and dilutive potential common shares outstanding
during the period. Dilutive potential common shares represent shares issuable
upon the exercise of outstanding options and are calculated using the treasury
stock method. Options to purchase shares of the Company's common stock for the
three and nine months ended September 30, 1997 were not included in the
computation of diluted earnings per share because their effect would have been
antidilutive. Options to purchase 10,000 shares of the Company's common stock at
September 30, 1998 were not included in the computation of diluted earnings per
share because their exercise prices were greater than the average market price
of the Company's common stock of $2.58 per share. Weighted average dilutive
options of 132,000 and 87,000 were used in the computation of earnings per share
for the three and nine month periods ending September 30, 1998, respectively.

        Effective March 24, 1998, the Company engaged in a stock option exchange
program that repriced substantially all the then outstanding options having an
exercise price above the then current market price of $2.375. The repriced
options began vesting April 24, 1998 over a 48 month period. The exercise price
for all 463,480 options exchanged was $2.375.

2.      Inventory

        Inventory represents laboratory materials, collection materials and
products and is stated at the lower of cost or market. Cost is determined using
standard costs, including freight, that approximate actual costs on a first-in,
first-out basis. Inventory consisted of the following at September 30, 1998 and
December 31, 1997, respectively:



                                                             1998           1997  
                                                            ------        ------

                                                            $1,703        $1,609
                                                            ======        ======


3.      Debt

PharmChem maintains a revolving line of credit agreement ("Credit Agreement")
with a bank. In August 1998, the Company amended its Credit Agreement to provide
for $500,000 of additional borrowings under the revolver and for less
restrictive financial covenants. At September 30, 1998, the maximum that



                                       8
   9

could be borrowed and the amount outstanding under the Credit Agreement were
$5,638,000 and $3,258,000, respectively.


4.      New Accounting Pronouncements

        The Company has adopted Statement of Financial Accounting Standards
("SFAS") No. 130 "Reporting Comprehensive Income." Comprehensive income (loss)
includes net income (loss) and several other items that current accounting
standards require to be recognized outside of net income (loss).


5.      Reclassifications

        Certain reclassifications have been made to prior period amounts to
conform to current year presentation.

         of Operations

     Net sales for the three months ended September 30, 1998 increased
$1,274,000 (12.7%) to $11,311,000 in 1998 from $10,037,000 in 1997. Medscreen,
the Company's U.K. operation, reported a sales increase of $583,000 (55.7%) in
part due to the awarding of the drug-testing contract for H.M Prisons, one of
the largest agencies that conducts drug testing outside of the United States,
and higher maritime collection accounts throughout the world. Domestic analysis
revenues increased $644,000 (7.8%) reflecting increases across all customer
categories and higher average selling prices of 3.7%. The Company's domestic
specimen volume increased 3.6% from 1997 levels. Domestic product sales of
PharmScreenTM On-site Screening Devices and PharmChek(R) Drugs of Abuse Patch
(excluding analysis) increased slightly compared to the prior year period.

     Net sales for the nine months ended September 30, 1998 increased $3,192,000
(11.0%) to $32,290,000 in 1998 from $29,098,000 in 1997, principally due to a
sales increase of $1,756,000 (56.4%) at Medscreen and higher domestic product
sales of $829,000 (75.4%). Domestic average selling prices increased modestly
and specimen volume decreased slightly.

     Cost of sales for the three months ended September 30, 1998 decreased
$227,000 (2.7%) to $8,175,000 in 1998 from $8,402,000 in 1997. Cost of sales as
a percentage of net sales decreased to 72.3% in 1998 from 83.7% in 1997. Gross
profit as a percentage of net sales increased to 27.7% in 1998 from 16.3% in
1997, reflecting higher average selling prices and lower labor, material and
results transmission costs.

     Cost of sales for the nine months ended September 30, 1998 increased
$126,000 (0.5%) to $23,698,000 in 1998 from $23,572,000 in 1997. Cost of sales
as a percentage of net sales decreased to 73.4% in 1998 from 81.0% in 1997.
Gross profit as a percentage of net sales increased to 26.6% in 1998 from 19.0%
in 1997. The improvement in gross profit for the current year's quarter and nine
months reflects the realization of benefits of the Company's cost containment
program announced late in 1997.

        Selling, general and administrative (SG&A) expenses for the three months
ended September 30, 1998 increased $434,000 (20.4%) to $2,558,000 in 1998 from
$2,124,000 in 1997. SG&A expenses as a percentage of net sales increased to
22.6% in 1998 from 21.3% in 1997.

        SG&A expenses for the nine months ended September 30, 1998 increased
$1,336,000 (21.4%) to $7,570,000 in 1998 from $6,234,000 in 1997. SG&A expenses
as a percentage of net sales increased to 23.4% in 1998 from 21.4% in 1997. The
increase in SG&A expenses for the quarter and for the year-to-date periods
represents higher information systems expenditures and the continued rebuilding
of the sales, marketing and administrative infrastructure.

        Income from operations for the three months ended September 30, 1998 was
$520,000 compared to a loss of $564,000 for the comparable period in 1997.
Income from operations for the nine months ended September 30, 1998 was $832,000
compared to a loss of $1,024,000 for the comparable period in 1997. The Company
recorded a provision for income taxes of $97,000 for the third quarter and of
$178,000 for the nine month period ending September 30, 1998, attributed
principally to its UK operations.

        Net income for the three months ended September 30, 1998 was $344,000 or
$0.06 per diluted share in 1998 compared to a net loss of $662,000 or $0.12 per
diluted share in 1997. Net income for the nine months ended September 30, 1998
was $398,000 or $0.07 per diluted share in 1998 compared to a loss of $1,307,000
or $0.23 per diluted share in 1997.


LIQUIDITY AND CAPITAL RESOURCES

        The Company's operations during the nine month period ended September 30
provided cash of approximately $3,339,000 in 1998 and $174,000 in 1997. The
improvement in cash flow from operations between 1998 and 1997 principally
reflects the current period's net income and increased current liabilities. As
of September 30, 1998, the Company had $895,000 in cash and cash equivalents.
During the nine months ended September 30, 1998, the Company used approximately
$1,714,000 in cash to acquire property and equipment, principally for
information systems and laboratory equipment.

        The Company maintains a Credit Agreement with a bank. All borrowings are
secured by a lien on all assets of the Company. The Credit Agreement provides
for borrowings under the revolver limited to 85% of qualified accounts
receivables up to a maximum of $6,000,000. At September 30, 1998, the maximum
that could be borrowed was $5,638,000 and approximately $3,258,000 was
outstanding under the Credit Agreement. Year-to-date net repayments on the
revolver were approximately $823,000 as of September 30, 1998. The Credit
Agreement contains certain financial covenants which, among others, require the
Company to maintain certain levels of net worth, cash flow and profitability,
and restricts the 



                                       11
   12

payment of dividends. As of September 30, 1998, the Company was in compliance
with its financial covenants.

        In August 1998, the Company amended its Credit Agreement to provide for
$500,000 of additional borrowings under the revolver and for less restrictive
financial covenants.

        The Company anticipates that existing cash balances, amounts available
under existing and future credit agreements and funds to be generated from
future operations will be sufficient to fund operations and forecasted capital
expenditures through 1998.

IMPACT OF RECENT ACCOUNTING PRONOUNCEMENTS

        In June 1997, the FASB issued SFAS No. 130 "Reporting Comprehensive
Income." SFAS No. 130 establishes standards for reporting and displaying
comprehensive income and its components in general-purpose financial statements
and is effective for fiscal years beginning after December 15, 1997.
Comprehensive income includes net income and several other items that current
accounting standards require to be recognized outside of net income. The Company
adopted the SFAS No. 130 disclosures in its 1998 consolidated financial
statements.

YEAR 2000

        The Year 2000 ("Y2K") issue is the result of date-sensitive devices,
systems and computer applications that were deployed using two digits rather
than four digits to define the applicable year. Therefore, these technologies
may improperly recognize a year containing "00" as 1900 rather than the year
2000. This may result in a system failure or miscalculations causing disruptions
of operations. The Company is subject to various risks associated with the Y2K
impact on information systems software and hardware.

        The Company began its evaluation of and action steps to correct Y2K
problems at the end of 1995 when it recorded a one-time restructuring charge of
$8.8 million, which included $1.9 million to write-down certain information
systems ("IS" assets). All of the IS assets written-down were inadequate to move
the Company forward operationally. For the period January 1, 1996 through
September 30, 1998, the Company has invested $5.0 million in new IS assets and
related equipment which have been designed to enhance its operational
capabilities as well as meet Y2K requirements.

        The Company has completed its assessment of the Y2K impact on internal
information systems. The assessment identified operational inefficiencies and
Y2K non-compliance of the existing laboratory information system ("LIS"). The
Company has decided to replace its existing LIS with a new system that is also
Y2K compliant. It is estimated that the decision process on vendor selection
will be completed by the end of this year with implementation scheduled for the
third quarter of 1999. The Company estimates the cost to purchase and install
the new LIS and related hardware will be $750,000 to $1 million. Excluding the
LIS expenditures, the Company estimates additional Y2K related expenditures of
approximately $100,000 representing consulting costs and payroll for employees
dedicated to Y2K projects. The Company expects to complete all Y2K projects by
the end of the third quarter of 1999. All investments in information systems
have been funded by internally generated cash, leases or bank financing.


                                       12
   13

        Due to the large volume of electronic transmissions, the Company is
conducting inquiries of customers and key business partners to identify Y2K
issues. The Company has contacted all of its critical vendors informing them it
will require written confirmation that such vendors can be Y2K compliant by the
end of 1998. Customers, business partners and vendors responses are currently
being reviewed and evaluated. During the next several months, the Company plans
to commence transmission of test results to its customers using a four digit
year to determine which customers can and cannot receive such electronic results
with a year field of four digits. The Company's internal drug test results
reporting systems have been reprogrammed and tested in a parallel systems
environment and the Company continues to test external results reporting
services.

        The Company is in the process of developing contingency plans that
consider scenarios whereby Y2K compliance is not significantly achieved by the
Company and/or its key customers, business partners and vendors. The Company
believes that the "most reasonably likely worst case Year 2000 scenario" would
result from a failure of third party transportation systems which would prevent
the Company from receiving specimens to test. These contingency plans, including
scenarios involving providers of transportation services, are expected to be
developed in mid-1999. Due to the general uncertainty inherent in the Y2K
issues, resulting in part from the uncertainty of Y2K readiness of third party
providers, suppliers and customers, the Company is unable to determine at this
time whether the consequences of Y2K non-compliance will have a material impact
on the Company's results of operations, liquidity or financial position.

Item 5. Other Information

        (a)  Shareholder Proposals

             The deadline for submission of shareholder proposals pursuant to
             Rule 14a-8 under the Securities Act of 1934, as amended, for
             inclusion in the Company's proxy statement for its 1999 Annual
             Meeting of Shareholders is December 18, 1998. Additionally,
             pursuant to the Company's By-laws, as amended, if a shareholder
             desires to bring business before an annual meeting of shareholders
             and does not attempt to have a proposal included in the proxy
             statement, the shareholder must give timely written notice to the
             Secretary of the Company before the annual meeting. To be timely, a
             shareholder's notice must be delivered to and received by the
             Secretary of the Company at least ninety days in advance of the
             anniversary date of the preceding year's annual meeting. The
             Company's 1998 Annual Meeting of Shareholders was held on May 19,
             1998. Accordingly, a shareholder must provide written notice of
             shareholder business no later than February 19, 1999. Shareholder
             proposals not delivered and received by this date will be
             considered untimely.
