اختبار زمن الثرومبين

لا يوجد نطاق مرجعي معتمد

There is no generally applicable reference interval for thrombin time. The result depends on the reagent the laboratory uses, and Dutch laboratories therefore publish values that barely overlap: UMC Utrecht uses 10.6-16.6 seconds, LUMC 15.3-18.7 seconds and Franciscus Gasthuis 15-22 seconds. A thrombin time of 12 seconds would be normal at one laboratory and low at another. We therefore state no number: read your result against the reference interval of the laboratory that performed the test.
