            VIROLOGIC ANNOUNCES FIRST QUARTER 2004 FINANCIAL RESULTS

             -- Company Reports 29 Percent Revenue Growth over First
              Quarter of 2003 and Generates Cash from Operations --

SOUTH SAN FRANCISCO, CALIF., May 3, 2004 -- ViroLogic, Inc. (NASDAQ: VLGC) today
reported financial results for the three months ended March 31, 2004.

The Company reported revenue of $9.0 million for the first quarter of 2004, an
increase of 29 percent over revenue of $7.0 million for the first quarter of
2003. The year-over-year growth was attributable to the Company's patient
testing business, which rose to $5.8 million from $5.3 million in the first
quarter of 2003, and its pharmaceutical business, which increased 128 percent to
$2.9 million from $1.3 million for the same period in 2003.

Gross margin was 49 percent in the first quarter of 2004 compared to 42 percent
reported during the same quarter last year. Gross margin improvement was driven
by improved efficiencies in laboratory operations as well as an increased
contribution from pharmaceutical revenues during the quarter. Operating costs
and expenses for the first quarter of 2004 were $10.3 million, compared to $9.5
million for the same period in 2003, due to higher costs associated with
increased sample volume and a charge of $0.4 million for the termination of the
Company's lease for original laboratory and office space. This early termination
enabled the Company to eliminate operating expenses related to this lease going
forward and reduce its aggregate remaining obligation by approximately half.

Net loss for the first quarter of 2004, including the lease termination charge,
was $1.2 million, or $0.02 per common share, compared to a net loss of $2.5
million, or $0.09 per common share, for the same period in 2003.

In the first quarter of 2004, the Company recorded stock dividends to preferred
stockholders of $0.1 million, resulting in net loss applicable to common
stockholders of $0.02 per common



share. In the first quarter of 2003, the Company recorded a non-cash deemed
dividend to preferred stockholders of $2.2 million resulting from a warrant
exchange relating to the sale of Series C Convertible Preferred Stock, and
recorded stock dividends to preferred stockholders of $0.5 million, resulting in
net loss applicable to common stockholders of $0.18 per common share.

The Company generated cash from operations during the first quarter of 2004, and
reported $10.3 million of cash, cash equivalents, short-term investments and
restricted cash at March 31, 2004.

RECENT HIGHLIGHTS

         -        Entered expanded distribution agreement with Quest Diagnostics
                  under which Quest Diagnostics will make ViroLogic its
                  preferred provider of HIV phenotypic testing. The agreement
                  will increase access to the Company's line of phenotypic
                  testing products, PhenoSense GT(TM) combination assay and
                  PhenoSense(TM) HIV, throughout Quest Diagnostics' national
                  network of laboratories, with more than 30 full-service
                  regional laboratories in major metropolitan areas and nearly
                  2,000 conveniently located patient service centers, where
                  patients' specimens are collected;

         -        Launched VLink online reporting system offering a fast and
                  convenient way for healthcare professionals to access patient
                  test results via a secure Internet connection;

         -        Presented 19 studies at the international retrovirus
                  conference in February in San Francisco. Among the highlights
                  were a study demonstrating the value of ViroLogic's
                  Replication Capacity assay as a tool to predict HIV disease
                  progression in untreated patients, studies exemplifying how
                  its neutralization assay can be used to characterize targeted
                  antibody responses which are relevant for vaccine development,
                  and studies showing the Company's expanding capability to
                  support the numerous biopharmaceutical companies now
                  developing entry inhibitor drugs to treat HIV; and

         -        Completed CLIA validation of ViroLogic's HIV-1 Co-receptor
                  Tropism Assay for use in clinical trials. This newly developed
                  assay accurately and reproducibly determines whether each
                  patient virus uses the CCR5 and/or CXCR4 co-receptor to infect
                  new cells. Consequently, it has become an important tool to
                  identify patients who are most likely to respond to treatment
                  with specific inhibitors of CCR5 or CXCR4 binding and monitor
                  the emergence of viral variants throughout clinical trials.
