Guide. An alanine aminotransferase (ALT) test measures the amount of this enzyme in the blood. ALT is found mainly in the liver, but also in smaller amounts in the kidneys, heart, muscles, and pancreas.ALT was formerly called serum glutamic pyruvic transaminase (SGPT).ow levels of ALT are normally found in the blood. But when the liver is damaged or diseased, it releases ALT into the bloodstream, which makes ALT levels go up.
The Biceps Brachii (commonly called the biceps) is a muscle located at the front of the upper arm and attaches your arm bone (humerus) to your shoulder.
The brachialis muscle is located in the upper arm. It lies underneath the biceps muscle. It acts as a structural bridge between the humerus, which is the bone of the upper arm, and the ulna, which is one of the forearm bones. The muscle is innervated by both the musculoskeletal nerve and the radial nerve. In some people, the muscle may appear doubled.
