MADISON,  Wis., July 25, 2006--Third Wave Technologies Inc. (Nasdaq: TWTI) today
reported its financial results for the second quarter ended June 30, 2006.

      Third Wave reported clinical molecular  diagnostic revenue of $5.1 million
for the second  quarter of 2006,  an increase of 18% and 7% from the  prior-year
quarter  and the  previous  quarter,  respectively.  The company  reported  $1.6
million of  research  revenue  during the second  quarter,  including  nearly $1
million of Agbio  revenue.  Total  revenues for the quarter ended June 30, 2006,
were $6.8  million,  an increase of more than 15% from $5.8  million  during the
same period of 2005.

      Clinical molecular  diagnostic revenue for the six-month period ended June
30, 2006,  increased  32% to $9.8 million,  compared to $7.4 million  during the
same period of 2005. Total revenue for the six-month period ended June 30, 2006,
increased 13% to $14.6  million,  compared to total revenue of $12.9 million for
the same period of 2005.

      Third Wave  reported a net loss of $4.7 million,  or ($0.11) a share,  for
the quarter  ended June 30,  2006,  compared to a net loss of $5.5  million,  or
($0.13) a share, for the same period of 2005. The company's  second-quarter 2006
net loss improved 35% from its pro forma net loss of $7.2 million,  or ($0.18) a
share, for the comparable period of 2005, with FAS No. 123(R) stock compensation
costs included in both periods.

      The company's net loss for the six-month  period ended June 30, 2006,  was
$9.1 million,  or ($0.22) a share,  compared to a net loss of $9.9  million,  or
($0.24) a share for the same  period of 2005.  Including  FAS No.  123(R)  stock
compensation  costs,  the company's pro forma net loss for that six-month period
of 2005 was $13.1 million, or ($0.32) a share.

      Third Wave  reported  gross  margins of 72% for the quarter ended June 30,
2006, compared to 69% for the same period of 2005. Total operating expenses were
$11.9  million for the second  quarter,  compared to $11.5  million for the same
period of 2005. The company's pro forma total operating  expenses for the second
quarter of 2005,  including FAS No. 123(R) stock compensation  costs, were $13.2
million.  Total operating expenses for the six-month period ended June 30, 2006,
were $24.4  million,  compared to $23.1 million for the same period of 2005. The
company's pro forma total



operating  expenses for the six-month period ended June 30, 2005,  including FAS
No. 123(R) stock compensation costs, were $26.3 million.

      Third Wave ended the second  quarter of 2006 with cash,  cash  equivalents
and short-term  investments of $36.2 million,  compared to $38.7 million at Dec.
31, 2005.

      Third Wave said the  company's  product  development  efforts  continue to
progress well. All of the company's current pipeline products remain on track or
ahead of schedule,  including the  submission of its  high-value HPV products to
the  U.S.  Food  and  Drug  Administration  in  2007.  The  company  anticipates
submitting two HPV products to the FDA: a 14-type,  high-risk screening test and
a genotyping test for types 16 and 18 of the virus.

      Third Wave announced that it would continue its focus on the highest-value
molecular  diagnostic  markets  by  launching  reagents  for  the  detection  of
chlamydia and gonorrhea in 2007. These products will complement Third Wave's HPV
offering. Taken together, testing for HPV, chlamydia, and gonorrhea accounts for
more than 20% of the molecular diagnostic testing market.

      The company also said that it will launch its  Universal  Invader(R)  Plus
program  earlier  than  anticipated.  External  evaluations  of the  program  by
customers have progressed well and generated outstanding results.

2006 Outlook Update

      Third Wave raises its guidance on clinical molecular diagnostic revenue to
$20-21 million for the year 2006. The company  anticipates  continued  growth in
its Agbio  revenue,  but does not expect any  material  contribution  of genomic
research  revenue  during the balance of 2006.  It is  maintaining  its previous
guidance of approximately $7 million in total research revenue and, as a result,
anticipates total revenue of $27-28 million for the year 2006.

      "Third Wave continued to make outstanding progress towards our 2006 goals,
with excellent, ongoing revenue growth in our core clinical molecular diagnostic
business that exceeded our  expectations,"  said Kevin T. Conroy,  president and
chief  executive.  "All of us at Third Wave are  dedicated  to  building  on the
growth of the  first  half of the year to meet or exceed  our  expectations  for
2006."
