SGPT (ALT)
₹131.00
An ALT test measures the level of alanine aminotransferase, also called ALT or SGPT. ALT is one of the enzymes that help the liver convert food into energy. High levels of these enzymes can be a sign that the liver is injured or irritated, and the enzymes are leaking out of the liver cells.
Why Are ALT Tests Done?
An ALT test may be done if a child has signs of a possible problem with the liver, such as jaundice (yellowish skin or eyes), dark urine, nausea, vomiting, or belly pain. It also might be done if a child is on medicine that makes high liver enzyme levels more likely.
How Should We Prepare for an ALT Test?
Your child may be asked to stop eating and drinking for 8 to 12 hours before the ALT test. Tell your doctor about any medicines your child takes because some drugs might affect the test results.
Wearing a T-shirt or short-sleeved shirt for the test can make things easier for your child, and you also can bring along a toy or book as a distraction.
How Is an ALT Test Done?
Most blood tests take a small amount of blood from a vein. To do that, a health professional will:
clean the skin
put an elastic band (tourniquet) above the area to get the veins to swell with blood
insert a needle into a vein (usually in the arm inside of the elbow or on the back of the hand)
pull the blood sample into a vial or syringe
take off the elastic band and remove the needle from the vein
In babies, blood draws are sometimes done as a “heel stick collection.” After cleaning the area, the health professional will prick your baby’s heel with a tiny needle (or lancet) to collect a small sample of blood.
Collecting a sample of blood is only temporarily uncomfortable and can feel like a quick pinprick.
