High bilirubin can point to different issues depending on whether direct or indirect bilirubin is elevated. Low bilirubin is usually not concerning. Learn how to interpret patterns, symptoms, limitations, and next steps.
A self-pay GGT blood test can cost about $18–$70 depending on the provider and mandatory fees. Compare total cost, lab network, state availability, and whether a liver panel with GGT is a better value.
A high or low alkaline phosphatase result can point toward liver, bile duct, bone, nutrition, thyroid, pregnancy, growth, or medication-related causes. Learn how ALP is interpreted with other labs and what to ask next.
An alkaline phosphatase blood test measures ALP enzyme activity, most often to help evaluate liver, bile duct, or bone conditions. Learn what high and low results can mean, how to prepare, and what follow-up tests may be used.
Compare alkaline phosphatase blood test cost for self-pay lab ordering, including standalone ALP tests, CMP panels that include ALP, mandatory fees, preparation, and when a broader panel may be the better value.
AST is a liver enzyme marker, but it can also rise from muscle, heart, and other tissue injury. Learn how high and low AST results are interpreted with ALT, bilirubin, ALP, symptoms, and repeat testing.
An AST blood test measures aspartate aminotransferase, an enzyme found in the liver, muscles, heart, and other tissues. Learn what AST results can mean, how to prepare, what can affect the test, and when follow-up testing may be needed.
Self-pay AST blood test prices can range from low-cost liver panels to higher standalone orders. Compare total costs, fees, panels, and preparation tips.
ALT is a liver enzyme often reported on a comprehensive metabolic panel or liver panel. Learn what high and low ALT results can mean, what commonly affects ALT, when to follow up, and what to ask about next.
Compare self-pay ALT blood test costs, mandatory fees, collection options, and when a liver panel or CMP may be a better value than ordering ALT alone.
