Alkaline Phosphatase Bone Fraction
Alkaline Phosphatase [ALP] is an enzyme that is found throughout the body, with the highest concentration present in bones and liver.
What is ALP Bone Fraction test?12
The level of ALP enzyme increases due to increased bone cells activity or any other condition which affects bone growth.
An ALP bone fraction test measures the level of ALP in blood. It is performed to detect several bone conditions such as bone cancers, osteoporosis, or Paget’s disease (a condition which causes malformed bones). It is also performed to monitor treatment for different bone diseases.
An ALP test is also performed to detect liver diseases.
Why is ALP bone fraction test suggested?12
This test is ordered if the doctor feels you might be having a bone disease when the following symptoms show:
- Bone/joint pain.
- Deformed bones/brittle bones.
- Increased occurrence of fractures.
How is ALP bone fraction test performed?12
An ALP bone fraction test is a blood test. The nurse/lab technician rinses the skin with an alcohol pad, inserts a needle into a vein on the rinsed skin, draws the blood and stores it in a small vial. You may feel a slight pinch. The nurse will place a dressing strip on the skin immediately after the process.
The blood sample is sent to the laboratory for diagnosis. The blood sample is taken from a vein visible on the inside of the elbow or the back of the hand.
Preparation before performing ALP bone fraction test 3
You should not eat or drink anything 6 hours before the test, unless stated otherwise by your doctor.
Your doctor might ask you to stop taking any medicines before the test as they may interfere with the test result. Consult your doctor before taking any medicines before the test.
Post-care after ALP bone fraction test 4
To reduce the occurrence of side effects, the following precautions must be taken:
- Do not remove the dressing strip before 30 minutes to an hour.
- Avoid wearing tight clothes on the arms.
- Avoid straining the arms through sports or exercise. Rest them as much as possible.
- If bleeding occurs, apply pressure with your fingers on the needle site.
- If swelling occurs, elevate your arm and place ice on the injected site for 10 minutes.
An ALP bone fraction test does not completely diagnose a disease. It only narrows down the list of causes for the symptoms. Further tests need to be performed to confirm the kind of bone disease you have.
Side effects/risks of ALP bone fraction test
Side effects of the blood test might include:
- Slight bruising or throbbing on the needle site.
