What common laboratory test is conducted before starting a statin?

The common laboratory test conducted before starting a statin is liver function tests. Statins are medications used to lower cholesterol levels, but they can affect liver enzymes. Monitoring liver function is essential because it allows healthcare providers to identify any potential liver injury or dysfunction that could occur as a side effect of the medication. Baseline liver function tests are typically performed to ensure that the patient has normal liver enzyme levels before initiating treatment with a statin. If there are abnormalities in these tests prior to starting therapy, it may suggest an underlying condition that could be exacerbated by statin therapy. By establishing a baseline, clinicians can also monitor for changes in liver function during treatment, ensuring the patient's safety.
