The Alanine Transaminase (ALT) test, also known as serum glutamate-pyruvate transaminase (SGPT), analyses ALT levels in the blood and is generally found inside liver cells. The ALT enzyme is released into the bloodstream when the liver is injured or inflamed. This procedure aids in the early diagnosis of any liver damage. Before other symptoms such as jaundice, black urine, and vomiting develop, an increase in ALT (SGPT) is the first sign of a problem. Higher-than-normal ALT levels can signify liver disease caused by hepatitis, cirrhosis, or liver tissue death. Lower ALT levels (within the normal range) suggest a healthy liver, while extremely low ALT levels may pose a health danger. The SGPT normal range in Delhi is from 0 to 45 units per litre of blood serum. An SGPT test is required regularly to monitor the health of the liver. The labs for the SGPT test in Delhi are trustworthy and certified. You do not need to perform any special preparation before the testing of SGPT ALT in Delhi.
