ALP – blood test

ALP – blood test


Alkaline phosphatase (ALP) is a protein found in all body tissues. Tissues with higher amounts of ALP include the liver, bile ducts, and bone.


A blood test can be done to measure the level of ALP.

The test is performed :

  • To diagnose liver or bone disease

  • To check, if treatments for those diseases are working

  • As part of a routine liver function test


How the Test is Performed?


A blood sample is needed. Most of the time, blood is drawn from a vein located on the inside of the elbow or the back of the hand. At  SOUTH PUNJAB LAB this test is performed on ROCHE ROUTINE CHEMISTRY.


How to Prepare for the Test?


You should not eat or drink for 6 hours before the test unless your health care provider tells you otherwise.


Many medicines can interfere with blood test results.

  • Your provider will tell you if you need to stop taking any medicines before you have this test.

  • DO NOT stop or change your medicines without talking to your provider first.


How does the Test Will Feel?


You may feel slight pain or a sting when the needle is inserted. You may also feel some throbbing at the site after the blood is drawn.
