Baseline assessment before starting a PCSK9 inhibitor?

Starting a PCSK9 inhibitor is guided by establishing the patient’s current LDL-C level to set a baseline and then measure how well the therapy lowers it. A baseline lipid panel is essential because it gives you the exact LDL-C (and other lipid values) before treatment, which you use to assess the magnitude of response once therapy begins. PCSK9 inhibitors typically produce substantial LDL-C reductions, so having an initial value helps confirm efficacy and inform ongoing treatment decisions. Safety labs like liver enzymes and CK are not routinely required just to start these agents, since PCSK9 inhibitors have a favorable hepatic safety profile and are not associated with the same risk of hepatic injury or myopathy that sometimes prompts checks with other lipid-lowering therapies. Liver biopsy is unnecessary, and PT/INR isn’t part of the standard baseline workup for initiating a PCSK9 inhibitor. If additional concerns exist (such as suspected liver disease or bleeding risk), targeted testing can be considered, but the baseline lipid panel remains the priority.
