Fibrinogen and Factor VIII Activity – Test Update

Posted February 1, 2013

This will take effect January 28, 2013

Overview and Clinical Utility:

Effective January 28, 2013, PathGroup will implement in-house testing for Fibrinogen and Factor VIII Activity.  Fibrinogen is a coagulation factor (Factor I) produced by the liver, and is essential for blood clot formation.  Low levels of fibrinogen are associated with bleeding commonly secondary to liver disease or Disseminated Intravascular Coagulation (DIC).  Fibrinogen is an acute phase reactant and elevated levels may be associated with inflammation.  Increased concentrations are associated with increased risk of atherosclerosis.

The National Comprehensive Care Network goal of therapy is achievement of a “major molecular response” (MMR), defined as a 3-log reduction in BCR/ABL to ABL fusion product. MMR is associated with excellent progression free survival.

Beta-2-Microglobulin, Serum – Test Update

Posted October 21, 2013

This will take effect October 21, 2013

Overview and Clinical Utility:

Effective October 21, 2013, PathGroup will implement in-house testing for Beta-2-Microglobulin (B2M) Serum.  B2M is a low molecular weight protein found on the surface of most nucleated cells.  It forms the light chain component of the histocompatibility antigen and is eliminated via the kidneys. However, this is markedly increased in tubulo-interstitial disorders.  Raised serum levels of B2M are associated with renal disease and rheumatoid arthritis.  Elevated serum levels can also occur with systemic lupus erythematosus, malignant lymphoma and myeloma.

Drug Screening – Serum or Urine?

Posted October 23, 2013

Overview and Clinical Utility:

When screening for Drugs of Abuse (DOA), or when monitoring patients taking prescription pain medications, the specimen of choice is urine as opposed to serum or plasma.  Why Urine?  Urine is considered the gold standard; it is non-invasive and fast.  Samples are easy to collect and test and there is generally a longer window of detection than blood.  Drugs of abuse can be detected in urine for days to weeks after exposure, in contrast to blood detection which is generally in hours. For example, heroin has a half-life of 6 to 15 minutes in blood, but opiate metabolites may be detected in urine for 2 to 3 days.
