Lovastatin-Induced Platelet IgM Antibody, Serum/Plasma — Qualitative
A qualitative test that looks for IgM antibodies associated with lovastatin-related platelet immune reactions.
["A positive result may support a lovastatin-associated immune platelet reaction but must be interpreted with your blood counts and medication history."]

What is this test?
This test looks for IgM antibodies directed toward platelets in a serum or plasma sample. It is intended to help investigate a possible immune-mediated platelet reaction associated with lovastatin.
Why might I need this test?
Your clinician may order it if taking lovastatin is linked with a low platelet count, unusual bruising, or bleeding. It may be used as part of a broader evaluation for drug-induced immune thrombocytopenia.
How is the test performed?
A blood sample is collected and separated into serum or plasma. The laboratory then evaluates the sample qualitatively for the presence of lovastatin-associated platelet IgM antibodies.
How do I prepare for the test?
Fasting is usually not required, but follow any instructions provided by your clinician. Tell the laboratory about your medications and the timing of lovastatin use; do not stop prescribed medication without medical advice.
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 indicate an immune response involving platelets after lovastatin exposure and can support evaluation for drug-induced immune thrombocytopenia. It does not establish the diagnosis by itself and should be interpreted with platelet counts, bleeding symptoms, other laboratory findings, and medication timing. A negative result does not completely exclude a drug-related immune reaction.
Short name
