Fluvastatin-Induced Platelet IgG Antibody, Serum/Plasma — Qualitative
Detects platelet IgG antibodies associated with an immune reaction to fluvastatin, a possible cause of low platelet counts.

What is this test?
This blood test looks for IgG antibodies that react with platelets in the presence of fluvastatin. These drug-dependent antibodies can occasionally cause the immune system to destroy platelets.
Why might I need this test?
Your clinician may order this test if your platelet count is low or you have bleeding, bruising, or other signs of a platelet problem after taking fluvastatin. It may be used to help determine whether the medication caused an immune reaction.
How is the test performed?
A blood sample is collected and separated into serum or plasma. A laboratory then evaluates the sample for fluvastatin-dependent platelet IgG antibodies and reports the result as detected or not detected, according to the laboratory's method.
How do I prepare for the test?
Follow your clinician's instructions about taking fluvastatin. Because the result can depend on medication exposure, do not stop the medicine on your own unless your clinician tells you to do so.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result may support an immune reaction to fluvastatin that causes platelet destruction, sometimes called drug-induced immune thrombocytopenia. A not-detected result does not completely exclude a drug-related reaction, particularly if testing was done long after the medicine was stopped. Low platelets can also result from many other conditions, so this result should be interpreted with your symptoms, medication history, and other laboratory tests.
Short name
Fluvastatin-induced platelet IgG antibody
