                    Trinity Biotech Completes Acquisition of
                               Primus Corporation

DUBLIN, Ireland (July 21, 2005)....Trinity Biotech plc (NASDAQ: TRIB,
ISE:TRIB.I) ), a leading developer and manufacturer of diagnostic products for
the point-of-care and clinical laboratory markets, today announced that it has
completed the acquisition of Primus Corporation, a leader in the field of in
vitro diagnostic testing for haemoglobin A1c and haemoglobin variants.

Trinity Biotech has acquired Primus for US$12 million, consisting of a cash
consideration of US$9 million and a one year promissory note of US$3 million.
The shareholders of Primus will also be entitled to an additional consideration
of up to US$4.6 million depending on the growth of the business during the
remainder of 2005. The transaction is being funded entirely with bank
borrowings, thereby leaving Trinity's cash balances available for future
potential acquisitions.

Primus, a Kansas City, Missouri based corporation advised by Crosstree Capital
Partners, was founded in 1989 and employs 36 people in the manufacture of
glycohaemoglobin instruments and reagents to serve customers from physicians'
offices to the largest reference laboratories worldwide. Trinity is committed to
further developing the business from the Kansas City location.

Primus has demonstrated consistent sales and profit growth. Sales increased from
$3.6 million for the year 2001 to $7.9 million for the year 2004, a compound
annual growth rate of 30%. The acquisition will be earnings positive for Trinity
Biotech in 2005. As part of the transaction, Primus CEO and founder, Tom Reidy,
will remain with the Company and continue to direct the operations of Primus
within the Trinity Group.

Ronan O'Caoimh, Trinity Biotech CEO, commented "We are delighted to acquire
Primus which has a strong track record of growth and a unique patented
technology in the field of A1c testing. In particular, Primus has a strong
position in the US market for variant A1c testing with an estimated market share
of 35%. Trinity's distribution network through direct sales and worldwide
distributors can further expand the Primus sales effort and ultimately result in
a significant increase in the number of instruments placed above the current
level of approximately three hundred. We are also excited about the new Primus
Rapid Gel product which is currently awaiting FDA approval which we expect will
be granted in early 2006. The Rapid Gel product will compete in the US$100
million point-of-care A1c market and is based on the Company's unique boronate
affinity methodology. We are confident that Primus will make a significant
contribution to Trinity's growth in future years."

Tom Reidy, CEO and founder of Primus, commented "The acquisition of Primus by
Trinity will provide the company with access to the wider distribution base and
technical support infrastructure of Trinity's direct sales operations in the
USA, Germany and the UK and to its worldwide distributor network. We are very
excited at the opportunities this will present to continue the growth profile of
our business and to better serve our customers."

Trinity will provide additional information regarding the acquisition during its
second quarter earnings conference call on Thursday 28th July at 11.00am EST.
