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.
Structure[edit] It penetrates the coracobrachialis muscle and passes obliquely between the biceps brachii and the brachialis, to the lateral side of the arm; a little above the elbow it pierces the deep fascia lateral to the tendon of the biceps brachii and is continued into the forearm as the lateral cutaneous nerve of the forearm.
