Antigen-Induced Lymphocyte Proliferation Panel: Candida, Tetanus, TB (PPD)
Also known as: Tuberculin PPD (TB PPD), antigen-induced, Antigen-induced Cell Proliferation, Lymphocyte Stimulation, Candida
Use
This panel assesses the cellular immune response to specific antigens by measuring lymphocyte proliferation. It is useful in evaluating patients with suspected immunodeficiencies and helps in the diagnosis of cellular immune function disorders.
Special Instructions
The test requires a specific collection of specimens and handling procedures to ensure viable lymphocytes for assessment.
Limitations
The test may not detect subtle immune deficiencies or dysfunctions. Proliferation responses can be affected by factors such as medication, recent infections, or other health conditions.
