LAP (Leukocyte Alkaline Phosphatase) Score

The test requires a blood sample, which is drawn through a needle from a vein in your arm.

The risks are minimal and are similar to those involved in a regular blood draw, such as slight pain, bleeding, or bruising at the puncture site.

Certain medications can affect the LAP Score. Inform your doctor about any medications, supplements, or treatments you are undergoing.

The frequency of the LAP Score test varies depending on the patient's condition and the doctor's assessment. It may be done as part of the diagnostic process and periodically during treatment.

Yes, infections can cause an increase in the LAP Score due to the increased production of white blood cells.

Various factors such as infections, medications, bone marrow disorders, and the body's response to stress can affect the LAP Score.

Serum alkaline phosphatase measures the total activity of the enzyme in the blood, while LAP Score specifically measures the enzyme's activity in white blood cells.

phosphatase in white blood cells is believed to be involved in the process of fighting infections and is a part of the body’s immune response.

Fasting is not required for the LAP Score test. You can have the test done at any time.

Normal values can vary, but typically range from 20 to 100 units per liter (U/L). However, what is considered normal can vary between laboratories.

If your LAP Score is abnormal, it is important to discuss the results with your doctor, who may recommend further testing or a referral to a specialist, such as a hematologist.

Yes, LAP Score can be a useful tool in monitoring the response to treatment in patients with CML, as changes in the LAP Score can reflect changes in the disease activity.

In conclusion, the LAP Score is a valuable diagnostic test that can provide critical information about the activity of alkaline phosphatase in white blood cells. It is primarily used in the diagnosis and monitoring of chronic myelogenous leukemia but can also be indicative of other conditions affecting the bone marrow or immune system. As with any medical test, it’s important to discuss the results and any subsequent steps with your doctor.
