LOINC description : In thromboelastography, clot initiation time (R) is the time for a clot to reach an
amplitude of 2 mm, and clot formation time (K) is the time for clot firmness to increase
from 2mm (R) to 20 mm. A prolonged K is usually caused by poor platelet function,
low platelet count, fibrin polymerization disorders or fibrinogen deficiency. Higher
concentrations of heparin can also prolong K in the Kaolin or RapidTEG assay, but
not in Kaolin, RapidTEG, or Functional Fibrinogen assays containing heparinase. [PMID:
