Once the tolls on the canal had paid for its construction in 1882, they were eliminated. After the opening of the canal, additional canals were constructed to connect the Erie Canal to Lake Champlain, Lake Ontario, and the Finger Lakes. The Erie Canal and its neighbors became known as the New York State Canal System.
Serum Glutamic Pyruvic Transaminase or ALT is an enzyme found primarily in the liver but also to a lesser degree, the heart and other tissues. It is useful in diagnosing liver function more so than SGOT levels. Decreased SGPT in combination with increased cholesterol levels is seen in cases of a congested liver.
A GGT test may be ordered when results of the ALP test are high but other tests that are part of the liver panel (such as AST and ALT) are not increased. GGT may be ordered along with or as a follow up to other liver function tests when a person has signs or symptoms that suggest liver disease.
