Normal Range of Interferon-Gamma Levels Lab results are commonly shown as a set of values known as a "reference range", which is sometimes referred to as a "normal range". and includes measurement of the delayed type hypersensitivity response 48--72 hours after intradermal injection of PPD. Use of LPTs is effective in the early identification of disease risk, and in secondary prevention of disease. The QuantiFERONR TB Gold Plus (in Tube) assay is intended for use as an aid in diagnosis of TB infection. To determine whether whole blood composing between heparinized blood and ACD blood could be substituted for standard LPA using PBMC. The quantiferon test is used as an indirect test forMycobacterium tuberculosis infection and disease. Until 2001, the only test used to diagnose latent tuberculosis infection (LTBI) was the tuberculin skin test (TST). 71775-1. % A reference range includes the upper and lower limits of a lab test based on a group of otherwise healthy people.

By Barbie Cervoni MS, RD, CDCES, CDN. The MITOGEN-NIL value serves as the positive control for the patient specimen, demonstrating successful lymphocyte activity. Macrophages originate from blood monocytes that leave the circulation to differentiate in different tissues. By definition, a relative value test is one that measures specific components of blood, urine, or other lab samples and compares those values to what would be expected in a normal, healthy population.
