An automated CBC reports platelets 28 × 10^9/L with a platelet-clump flag. The patient has no bleeding symptoms and previous counts were normal. What is the best first laboratory response?
1Release the count as critical without review
2Examine a peripheral smear for clumps and obtain a properly collected specimen in an alternative anticoagulant if needed✓ 정답
3Manually change the platelet count to the previous value
4Incubate the EDTA tube overnight and repeat the count
해설
EDTA-dependent platelet clumping can produce a spuriously low count. Smear review confirms clumping, and prompt recollection using an alternative anticoagulant can help obtain a reportable platelet count.
