Point of care hemoglobin testing in plateletpheresis donors: Noninvasive versus invasive methods

摘要

BackgroundPredonation hemoglobin (Hb) for plateletpheresis donors is estimated by presently available invasive methods. Venous samples of only those donors whose Hb is more than 12.5 g/dl are screened for complete blood count and transfusion transmissible infections. There is a pressing need to substitute this invasive Hb test with noninvasive one to reduce donor discomfort and avoid further pricking the donor. We therefore went ahead with the aim of comparing a noninvasive Hb estimation method NBM 200 with the invasive method – Hemocue, taking SYSMEX KX-21 as a gold standard.
