Fluvastatin, Serum/Plasma — Mass Concentration
Measures the amount of fluvastatin, a cholesterol-lowering statin, in blood. This specialized test may help assess drug exposure in unusual clinical situations.
["An unexpected fluvastatin level may prompt a review of dosing, adherence, medication interactions, or the timing of the blood sample."]

What is this test?
This test measures the concentration of fluvastatin in serum or plasma. Fluvastatin is a prescription statin used to lower LDL cholesterol and reduce cardiovascular risk.
Why might I need this test?
Fluvastatin blood levels are not routinely checked for most people. A clinician may order this test in unusual situations, such as evaluating an unexpected treatment response, suspected nonadherence, medication interactions, or uncertain drug absorption.
How is the test performed?
A blood sample is collected and sent to a laboratory. The laboratory separates serum or plasma and uses a validated analytical method to determine the fluvastatin concentration.
How do I prepare for the test?
Fasting is usually not required, but follow any instructions from your clinician. Keep taking fluvastatin as prescribed unless your clinician tells you otherwise, and tell the laboratory when you last took a dose because timing can affect the result.
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.
Fluvastatin concentrations vary with the dose, time since the last dose, absorption, metabolism, and other medications. A level lower than expected may reflect missed doses, poor absorption, or an incorrectly timed sample, while a higher level may prompt review of dosing and interactions. The result should not be interpreted alone and does not by itself diagnose toxicity or organ injury; lipid levels and liver-related tests are more commonly used to assess treatment response and safety.
