                    NEOPROBE ANNOUNCES FIRST QUARTER RESULTS

              Revenues Increase by 45% and Net Loss Declines by 43%


DUBLIN, OHIO - May 8, 2003 -- Neoprobe Corporation (OTCBB: NEOP), a diversified
developer of innovative oncology and cardiovascular surgical and diagnostic
products, today announced consolidated operating results for the first quarter
of 2003. First quarter results included revenues of $1.5 million compared to
$1.1 million for the first quarter of 2002. In addition, Neoprobe reported a net
loss of $479,000 or $0.01 per share compared to a loss of $845,000 or $0.02 per
share for the comparable period in 2002. Total operating expenses were $1.2
million for the first quarter of 2003 compared to $1.4 million for the first
quarter of 2002.


David Bupp, Neoprobe's President & CEO said, "The operating results for the
first quarter reflect a continuation of positive trends in our gamma surgery
business and the impact of expense control initiatives implemented in 2002.
Revenues for the quarter were principally generated from the sales of gamma
surgery products, as we are in the initial stages of launching the Quantix(TM)
blood flow products. Quantix product revenues from demonstration unit shipments
were under $100,000 for the quarter; however, we anticipate that the revenue
contribution from Quantix products will build steadily over the coming quarters,
both from demonstrator and end-customer shipments. Marketing and sales
activities for the quarter were devoted to clinical and tradeshow activities
associated with the commercial launch of the first two Quantix products."

Year-to-date milestones:

     -    Issued the first patent covering the Quantix ADBF(TM) technology
          (January);

     -    Received notification of the allowance of claims on a second ADBF
          patent (February);

     -    Received clearance to market the Quantix/OR(TM) in Europe (March);

     -    Obtained $500,000 in bridge financing as a first step in our financing
          plans (April); and,

     -    Commenced shipment of the Quantix/OR to distributors in Europe and the
          Pacific Rim (April).

"Our most important goals for the year are still ahead of us," Bupp continued,
"and we remain confident that our business plan is on track toward the
achievement of these milestones."
