          NEOPROBE PROVIDES THIRD QUARTER RESULTS & DEVELOPMENT UPDATE
                            Conference Call Scheduled

DUBLIN, OHIO - November 3, 2005 -- Neoprobe Corporation (OTCBB: NEOP), a
diversified developer of innovative oncology and cardiovascular surgical and
diagnostic products, today announced consolidated operating results for the
third quarter of 2005. Third quarter results included net device sales of $1.3
million compared to $1.5 million for the third quarter of 2004. Year-to-date net
device sales for the first three quarters of 2005 were $4.5 million compared to
$4.1 million for the same period in 2004. In addition, Neoprobe reported a net
loss of $1.3 million or $0.02 per share compared to a loss of $239,000 or $0.00
per share for the comparable period in 2004. Neoprobe reported a year-to-date
net loss of $3.6 million for the first three quarters of 2005 compared to $1.3
million for the same period in 2004. The year-to-date net loss for the three
quarters of 2005 included $1.1 million in non-cash charges (consisting primarily
of amortization of intangible assets and amortization of warrant and
debt-issuance charges related to the financing that was completed in December
2004) compared to total non-cash charges of $575,000 through the first three
quarters of 2004.

Brent Larson, Neoprobe's Vice President, Finance and CFO, said, "Our
year-to-date device sales demonstrate continued strong performance from our
gamma device business. Continued growth in the out-of-warranty service and
extended service contract aspects of our gamma device business are helping
offset the effect of quarterly fluctuations in purchases from our primary device
marketing partner. Sales of our blood flow devices continued to provide only a
minor contribution to the increase in sales for the quarter. We are continuing
to train distributors and are starting to see increases in the number of device
evaluations in hospitals which we hope will translate into revenue as the
capital sales cycle is completed over the coming months. We believe the next six
months will be critical in evaluating the results from recent distributor
retraining and re-invigoration of the sales process for our Quantix/OR(TM)
device."

David Bupp, Neoprobe's President and CEO, said, "The increase in operating
expenses during the quarter over the prior year was primarily due to the costs
of non-clinical testing and drug manufacturing validation and production
activities associated with Lymphoseek(TM). Our development efforts continue to
move Lymphoseek forward, albeit not as rapidly as we had originally anticipated.
However, we believe that proactively following the guidance of FDA will
ultimately help us to avoid some of the recent regulatory disappointments
experienced in our industry and may expedite the review process for the drug. We
continue to expect our overall out-of-pocket development costs for Lymphoseek
will total approximately $5 million and that the contribution from our device
businesses will continue to cover the majority of our corporate overhead to
enable us to devote our resources to the development of recurring revenue
products."

Neoprobe also provided the following update to its drug and therapeutic
development initiatives.

Lymphoseek Development Update

Neoprobe continues to have an active dialogue with FDA regarding Lymphoseek and
believes the process is continuing to move forward in a positive manner. In late
September, Neoprobe received a letter confirming feedback from recent
discussions with FDA regarding the amendment to our Investigational New Drug
(IND) application. In its feedback, FDA formalized a very stringent non-clinical

                                     -more -

template for drug safety involving a total of seven tests. The original
Lymphoseek development timeline did not include plans for two repeat dose
studies that are being required as a part of the seven tests. We did not expect
to have to complete such extensive repeat dose testing due to our assessment
that the likelihood of any patient ever receiving two administrations of
Lymphoseek would be very low. However, all seven non-clinical tests, including
the repeat dose studies, have now been completed. Based on a review of the
preliminary reports from these tests, we are not aware of any drug-related
adverse findings. The completion of these non-clinical tests has taken longer
than our original estimates due to the availability of resources at the testing
labs and the extended timelines for completing the testing process as a result
of having to use radioactive compounds in the two repeat dose tests to detect
the presence of the drug.

FDA's September letter also confirmed that we will be required to use the final
commercial drug, produced under Good Manufacturing Practices (GMP) conditions,
in the conduct of the Phase II trial. Our original developmental timeline for
Lymphoseek had anticipated using drug produced by the University of California,
San Diego (UCSD) rather than commercially produced material. Our original
assessment was based on historical precedents from other similar drug products.
However, after evaluating the impact of FDA's requirement for us to use the
final commercial drug for the Phase II trial, we believe that while delaying the
start of the Phase II in order to answer FDA's chemistry, manufacturing and
controls (CMC) questions surrounding Lymphoseek will focus FDA's review of the
New Drug Application (NDA) on efficacy from the pivotal trial and ultimately put
us in a much stronger regulatory position once the NDA is filed.

It is now our plan to file the non-clinical study reports with FDA in December.
At roughly the same time, our drug manufacturing partners, Reliable
Biopharmaceuticals and Cardinal Health, will have completed their development
and validation work and have provided responses to the CMC questions raised by
FDA. The anticipated review cycle for the non-clinical and CMC information
should permit the current clinical hold to be released by FDA at roughly the
same time as commercial drug is available in the middle of the first quarter of
2006.

The effects of these changes have required that we adjust our timelines and
expectations for Lymphoseek. Prior to the most recent delays in completing the
battery of non-clinical safety studies and the requirement to use final
commercial material, we had hoped to start the Phase II in the fourth quarter of
2005 followed shortly thereafter by the pivotal trial. We now believe that
enrollment of patients in the Phase II trial will not be completed until
sometime during the first half of 2006 with the pivotal (i.e., Phase III) trial
starting in the second half of 2006. Our goal of filing the NDA by mid-year 2006
has now been revised to the end of 2006; however, we believe that strenuously
following the guidance we are receiving from FDA will ultimately pay dividends
in the review process for the NDA as we remain highly confident in the clinical
benefit and market potential of Lymphoseek. We continue to believe that
Lymphoseek can be commercialized in the later part of 2007 and that the drug, if
approved, should provide a significant positive financial contribution to
Neoprobe in 2008.

RIGScan(R) CR Development Update

Neoprobe recently filed a request to establish a corporate IND application for a
modified chimeric (i.e., humanized) version of RIGScan CR. With the
establishment of a corporate IND, responsibility for the clinical and commercial
development of this humanized version of RIGScan CR will be officially
transferred from a physician-sponsored IND to Neoprobe.

David C. Bupp, Neoprobe's President and CEO, said, "We believe moving forward
with a humanized version of RIGScan CR will address a number of concerns raised
by FDA and will ultimately result in a more producible, reliable and effective
drug. The potential partners we are in active discussions with, along with our
regulatory advisors and representatives from various regulatory agencies, have
all indicated a strong preference for using a humanized antibody in further
RIGScan CR development activities."

Neoprobe's contract statisticians have also recently concluded, based on data
published earlier this year on adjuvant post-operative chemotherapies for
colorectal cancer, that it will be necessary to increase the number of patients
in a proposed pivotal trial for RIGScan CR to approximately 2,200 in order to
show a statistically valid differential in time to recurrence between patients
treated using RIGScan CR versus other more traditional methods. Bupp continued
"We expect the increase in patients will cause an increase in the development
cost; however, we expect that the effect on the development timeline, once a
partner is secured and development commences, will be less than six months. We
continue to have active dialogue with multiple potential development partners
for RIGScan CR. We would characterize the tone of the discussions with the
various parties to be active and positive and we are working to conclude a
transaction. We have made each of the parties aware of the change in trial size
as a part of our ongoing discussions and will continue to update the
shareholders as events warrant."

Cira Biosciences Update

Cira Biosciences, Inc. fundraising efforts thus far have been unsuccessful. Bupp
commented, "The current state of the capital markets following recent biotech
failures has made it difficult to secure the resources we were originally
seeking. We are in the process of re-evaluating our capital needs and
investigating alternative, venture-based sources of funding."

Neoprobe's President and CEO, David Bupp, and Vice President and CFO, Brent
Larson, will provide a business update and discuss the company's third quarter
