What is DLC in a Blood Test
A DLC test, or differential leukocyte count, is a blood test that measures the number and types of white blood cells (WBCs) in your body. WBCs are an important part of your immune system, and they help to fight infection. The DLC test can help your doctor to diagnose a variety of conditions, including infections, allergies, and autoimmune diseases.
The DLC test is typically done as part of a complete blood count (CBC). The CBC also measures the number of red blood cells (RBCs), hemoglobin, and platelets.
The DLC test results are reported as percentages. The normal ranges for the different types of WBCs vary depending on your age and sex. However, the general ranges are as follows
* Neutrophils 55-70%
* Lymphocytes 20-40%
* Monocytes 2-8%
* Eosinophils 1-4%
* Basophils 0-1%
Abnormal DLC results can indicate a variety of conditions, including
* Infection A high number of neutrophils (neutrophilia) can indicate an infection. A low number of neutrophils (neutropenia) can also indicate an infection, but it can also be a sign of a more serious condition, such as leukemia.
* Allergies A high number of eosinophils (eosinophilia) can indicate an allergy.
* Autoimmune diseases A high number of lymphocytes (lymphocytosis) can indicate an autoimmune disease.
If your DLC results are abnormal, your doctor will likely order additional tests to determine the cause of your condition.
The DLC test is a simple and painless test that can provide valuable information about your health. If your doctor orders a DLC test, it is important to follow their instructions carefully so that you get accurate results.
Here are some additional things to keep in mind about the DLC test
* The DLC test is usually done in the morning, before you eat or drink anything.
* You may need to fast for 8-12 hours before the test.
* You may need to avoid taking certain medications before the test.
* The test itself is quick and painless.
* You should be able to resume your normal activities immediately after the test.
If you have any questions about the DLC test, be sure to talk to your doctor.
