Rosuvastatin-Induced Platelet IgG, Serum/Plasma — Qualitative, Flow Cytometry
Detects IgG antibodies that bind to platelets in the presence of rosuvastatin, which can help evaluate suspected immune-mediated thrombocytopenia.
["A positive result supports rosuvastatin-induced immune thrombocytopenia, especially when low platelets develop after starting the drug."]

What is this test?
This blood test looks for IgG antibodies that attach to platelets when rosuvastatin is present. These drug-dependent antibodies can cause the immune system to destroy platelets, leading to a low platelet count.
Why might I need this test?
It may be ordered if your platelet count is low or you have bruising, bleeding, or other symptoms after starting rosuvastatin. The result helps determine whether rosuvastatin may be contributing to immune-mediated thrombocytopenia.
How is the test performed?
A blood sample is collected and separated into serum or plasma. The laboratory uses flow cytometry to determine whether patient IgG binds to platelets in the presence of rosuvastatin.
How do I prepare for the test?
No special preparation is usually needed. Tell your clinician when you started rosuvastatin and when symptoms or low platelet counts began, and do not stop or change the 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 indicates that rosuvastatin-dependent platelet IgG is present and supports a diagnosis of drug-induced immune thrombocytopenia. A negative result does not completely exclude the condition, so results must be interpreted with the medication timeline, platelet count, symptoms, and other possible causes.
Short name
Rosuvastatin platelet antibody test
