ALP Blood Test - medical doctor by Kurhan

An ALP blood test is conducted to check the number of ALP enzymes within the blood. If the enzyme levels are high, it may be a sign of an underlying problem

The ALP enzymes can be found most abundantly in the liver, bone, intestines, kidneys and placenta. The liver is the most abundant source of the ALP enzymes. The ALP blood test is conducted to measure the amount of enzymes found within the body. If the enzyme count is too high, it can be a sign of a serious underlying health condition. If the enzyme count is high, it may be a sign that there are bone diseases present, damaged cells or other serious underlying health conditions. An ALP test is often conducted to check for damage to the liver or to check for liver diseases. It's often used to monitor patients who use medications that may cause liver damage. However, a doctor may require an ALP blood test to be conducted for other reasons as well, such as to check for an illness or to monitor existing conditions.

Preparation

This test is often conducted as a regular blood test, and usually no preparation is needed. However, if a follow up test is needed, you may be advised to not eat or drink anything for at least 10 hours prior to the blood test. Certain medications may interact with ALP levels; therefore, it's important to inform your lab technician about any medications you are taking.

Procedure

The test is conducted very similarly to other blood tests. An elastic band will be placed around your arm to stop the blood flow. This is done to allow the veins to expand and will allow the needle to be inserted easier. The injection site is cleaned well with alcohol before the needle is inserted into the vein to collect the blood.

At least one tube of blood will be collected to retrieve the ALP enzymes. After the adequate amount of blood has been collected, the elastic band will be removed for your arm to reestablish proper blood flow. As the needle is removed, a cotton ball or gauze pad will be placed over the injection site. Pressure and a bandage will be applied to stop the bleeding. The bleeding usually ceases within two minutes.

Risks

There are little risks associated with this test. The injection site can become sore and bruising may occur. There is a chance of infection if the injection site is not cleaned well. If you suffer from bleeding disorders, it may take you longer to stop bleeding after the test is conducted.
