ALT is majorly found in the liver cells, and smalltraces are also available in the kidney. ALT gets released into the bloodstream when there are damages in the liver or it gets inflamed. Due to this ALT serum level rises. Measuring this level in a blood, allows doctors to evaluate the health of an individual’s liver. ALT test is part of initial liver disease screening.

The procedure starts with taking a small blood sample and follows the below steps:

1- Healthcare provider will use an antiseptic for cleaning your skin where the needle will be inserted.

2- On upper arm, an elastic band will be tied which will stop the blood flow and will make the veins more visible.

If the results are higher than the normal ALT levels, that indicates liver damage. An ALT increase may be due to:

a- An inflammatory condition of the liver i.e. hepatitis
