ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         On July 21, 1997, Hycor Biomedical Inc. ("Hycor") acquired from
unrelated third parties all of the outstanding stock of Cogent Diagnostics
Limited ("Cogent"). Cogent is based in Edinburgh, Scotland.

         The aggregate consideration paid by Hycor for the shares was
$3,025,000, which consisted of $1,450,000 paid in cash at the closing and the
issuance by Hycor of secured promissory notes with a total principal amount of
$1,575,000.

         The cash portion of the purchase price was paid for by Hycor from cash
on hand and by borrowing approximately $1,000,000 under Hycor's revolving credit
facility with Tokai Bank, which credit facility was established in July 1997.
The notes issued by Hycor bear interest at 6.85% per year and may be prepaid by
Hycor without penalty after January 21, 1998. Accrued interest under the notes
is payable quarterly commencing October 21, 1997 and principal is payable in
three annual installments of $525,000 each, commencing July 21, 1998. Hycor's
obligations under the notes are secured by Hycor's pledge of the acquired Cogent
shares in favor of the selling shareholders.

         Cogent develops, manufactures and markets a broad line of test kits for
diagnosis of autoimmune disease. Hycor intends to continue to utilize the assets
of Cogent for the same purposes.

         Copies of the Share Purchase Agreement, form of Secured Loan Notes and
form of Shares Pledge between Hycor and selling shareholders of Cogent are
attached to this Form 8-K as exhibits and are incorporated herein.
