Method Description Describes how the test is performed and provides a method-specific reference

The STA Fibrinogen Kit is intended for the quantitative determination of fibrinogen in plasma by the Clauss clotting method. In the presence of an excess of thrombin, the clotting time of diluted plasma is inversely proportional to the level of plasma fibrinogen. The clot is detected by the STA-R Evolution. The STA-R Evolution is a fully automated coagulation instrument that uses an electromagnetic viscosity detection system. The oscillation of a steel ball within the cuvette with the thrombin and diluted plasma is monitored by the STA-R Evolution. At the constant viscosity; constant pendular swings of the ball are obtained within an electromagneticfield. As the viscosity increases as a result of the coagulation, the oscillation amplitude of the ball swing decreases. An algorithm uses these variations in oscillation amplitude to determine the clotting time. The time is read from a stored curve on the STA-R Evolution. An increase of the fibrinogen level is observed in cases of diabetes, inflammatory syndromes, and obesity. A decrease of the fibrinogen level is observed in DIC, fibrinolysis and hereditary diseases.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Monday through Sunday Continuously

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

1 day

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result

1 day

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

8 hours

Performing Laboratory Location The location of the laboratory that performs the test
