There is no need to stop your statin tablet before undergoing a Liver Function Test (LFT). Statins can occasionally cause mild elevations in liver enzymes (SGOT/AST and SGPT/ALT). The purpose of checking LFT while taking statins is to monitor their effect on the liver. Therefore, continue your prescribed statin without skipping doses and get the LFT done. Regarding your elevated triglycerides, Omega-3 fatty acids (EPA and DHA) can help reduce triglyceride levels. Prescription-strength omega-3 preparations, usually at a total dose of 4 grams per day, can reduce triglycerides by approximately 20–30%. However, omega-3 supplementation is not necessary for everyone. Its use depends on your triglyceride levels and overall cardiovascular risk. It should be started only after reviewing your lipid profile. Meanwhile, reducing sugar, refined carbohydrates, alcohol intake, and excess body weight, along with regular exercise, can significantly improve triglyceride levels.

Statins can cause a mild, temporary rise in liver enzymes in some people, so this kind of variation in LFT results while on the tablet is fairly common and usually not something to worry about on its own.
