FX13M - Specimen: Factor XIII, Qualitative, with Reflex to Factor XIII 1:1 Mix

Test Catalog

Test ID: FX13M    
Factor XIII, Qualitative, with Reflex to Factor XIII 1:1 Mix

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

If Factor XIII 1:1 has a result of Lysis, then Factor XIII, 1:1 Mix will be performed at an additional charge.

Specimen Type Describes the specimen type needed for testing

Plasma Na Cit

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Draw one 5 mL lt. blue (sodium citrate) tube. Separate immediately and submit 2 mL platelet-poor plasma, ship frozen.


Note: Critical frozen.  Separate specimens must be submitted when multiple tests are ordered.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

1 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected


Mild OK; Gross reject


Warm reject; Cold reject






Serum. Non-frozen or hemolyzed specimens


Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
