Clinical Laboratory Assistant Certification

The Clinical Laboratory Assistant Certification is a free beginner-level, 15-minute skill test from Science of Apps. It tests the knowledge of a clinical laboratory assistant or specimen processor — specimen collection basics and order of draw, specimen processing, handling, accessioning and transport, and laboratory safety, quality control and point-of-care testing — written to CLSI GP41 venepuncture guidance, the WHO Laboratory Biosafety Manual (4th edition), WHO guidance on transporting infectious substances and OSHA bloodborne pathogens rules for 2026. Always follow your laboratory's procedures. Score 70% or more on its 15 questions to earn a verifiable Clinical Laboratory Assistant Proficiency certificate (SOA-CLA). Every question is based on published standards and research — including CLSI GP41: Collection of Diagnostic Venous Blood Specimens (Clinical and Laboratory Standards Institute), Laboratory Biosafety Manual, 4th edition (World Health Organization), Bloodborne Pathogens Standard (29 CFR 1910.1030) (OSHA) — and each answer is explained with its source.
