Test Details
Leukocyte Adhesion Deficiency (LAD) is a rare genetic disorder that affects the immune system. There are two types of LAD: LAD I and LAD II. Both types are characterized by a deficiency in the ability of white blood cells (leukocytes) to adhere to the blood vessel walls and migrate to sites of infection or inflammation.
To diagnose LAD, various tests can be performed:
- Complete Blood Count (CBC): This test measures the number of different types of blood cells, including white blood cells. LAD patients typically have low levels of neutrophils, a type of white blood cell.
- Flow Cytometry: This test measures the expression of adhesion molecules on the surface of white blood cells. LAD patients show reduced or absent expression of these molecules.
- Genetic Testing: This test involves analyzing the patient’s DNA to identify mutations in the genes responsible for LAD. LAD I is caused by mutations in the ITGB2 gene, while LAD II is caused by mutations in the SLC35C1 gene.
- Adhesion Assay: This test measures the ability of white blood cells to adhere to a substrate. LAD patients show impaired adhesion compared to healthy individuals.
- Skin Biopsy: In some cases, a skin biopsy may be performed to examine the presence and function of adhesion molecules on white blood cells.
It is important to note that these tests should be performed by a qualified healthcare professional or a specialized laboratory. Additionally, the diagnosis of LAD should be confirmed by a geneticist or an immunologist.
