# The Blood Tests (Evidence of Paternity) Regulations 1971, Regulation 9: Testing of samples


(1) Samples taken for the purpose of giving effect to a direction shall (so far as practicable) all be tested by the same tester.
(2) A tester shall not make tests on any samples for the purpose of a direction unless he will, in his opinion, be able to show from the results of those tests (whether alone or together with the results of tests on any samples which he has received and tested or expects to receive subsequently) that a subject is or is not excluded from being the father of a subject whose paternity is in dispute.
