문제
An asymptomatic patient has a platelet count of 28 x 10^9/L. The analyzer flags platelet clumps, and clumps are seen at the feathered edge of the EDTA smear. What is the best next step?
1Report severe thrombocytopenia with a note that platelet clumps were observed on smear
2Recollect in an alternative anticoagulant according to laboratory policy and verify the count✓ 정답
3Estimate platelet count from the hemoglobin concentration and red cell indices
4Warm the EDTA specimen to 37°C for 15 minutes and reanalyze immediately
해설
EDTA-dependent platelet clumping can cause pseudothrombocytopenia. Recollection using a validated alternative anticoagulant and smear review can provide a more accurate count.
