Reference Range
Thrombin time is a screening coagulation test designed to assess fibrin formation from fibrinogen in plasma.
The reference range for the thrombin time is usually less than 20 seconds (ie, 15-19 seconds), but this depends on the test kit/instrumentation used in the laboratory. Healthy infants up to age 6 months may have a slightly prolonged thrombin time by 2-3 seconds.
