LOINC description : Platelet large cell ratio (P-LCR) is the ratio of platelets larger than 12 fL and
smaller than 30 fL divided by the total number of platelets counted (fL (femtoliter)
is the metric unit of volume equal to 10*-15 liters). P-LCR is one of the platelet
volume indices estimated by automated blood cell analyzers and useful for various
diagnoses of abnormal platelet counts. An elevated P-LCR is seen in patients with
hyperlipidemia and suggests the possible risk of thrombosis. Larger platelets are
more reactive and may add to vaso-occlusive events in patients with dyslipidemia.
P-LCR may be useful as an indicator of risk for thromboembolic ischemia events.[PMID:
