Analysis Note |
Activity is expressed in NIH units obtained by direct comparison to a NIH Thrombin Reference Standard, Lot J. |
|
The NIH assay procedure uses 0.2 mL of diluted plasma (1:1 with saline) as a substrate and 0.1 mL of thrombin sample (stabilized in a 1% buffered albumin solution) based on a modification of the method of Biggs. Only clotting times in the range of 15-25 seconds are used for determining thrombin concentrations. |
