Fib Clauss
Fib Clauss is a functional clotting assay used for quantification of fibrinogen in citrated plasma. Fib Clauss reagent utilises the Clauss technique, where a high concentration of thrombin is added to pre-diluted plasma and the clotting time is measured. The clotting time depends on the level of functional fibrinogen in the sample. Fib Clauss reagent has a large linear range, up to 8 g/L, limiting the number of re-analyses.
