It is knew to cause cell shrinkage and may result to falsely low HCT and ESR.
- A.
Heparin
- B.
Citrate
- C.
Double Oxolate
- D.
EDTA
Correct Answer
D. EDTAExplanation
EDTA, or ethylenediaminetetraacetic acid, is a commonly used anticoagulant in blood collection tubes. It works by chelating or binding calcium ions, which prevents the clotting of blood. However, EDTA has been known to cause cell shrinkage, leading to falsely low hematocrit (HCT) and erythrocyte sedimentation rate (ESR) results. This is because the shrinkage of red blood cells can result in a decrease in volume, leading to a lower HCT measurement. Similarly, the aggregation of red blood cells caused by cell shrinkage can affect the settling rate, resulting in a lower ESR measurement.Rate this question:
