Medical professionals use the Nitroblue tetrazolium test as a diagnostic tool to check the capacity of white blood neutrophils to form reactive oxygen species. The NBT test stands as a vital diagnostic method for identifying chronic granulomatous disease (CGD) which weakens immune systems and makes patients highly vulnerable to infections from bacteria as well as fungi. The neutrophils receive NBT dye exposure during this process and the dye shows color reaction after reactive oxygen species production. A healthy response will cause the NBT Blood test solution to turn deep blue or purple whereas no reactive color change indicates a deficiency in immune system function.
Doctors will prescribe the Nitroblue tetrazolium test to diagnose patients who exhibit multiple bacterial or fungal infections and slow healing of wounds, organ abscess development, and severe pneumonia. Healthcare providers administer the NBT test to affected individuals as well as their blood relatives to determine who is a carrier or has an unknown case of CGD because this disorder has genetic roots. The NBT test enables quick detection which results in proper treatment and improved control of immune system weaknesses.
During the Nitroblue tetrazolium test procedure, the healthcare provider obtains a small blood sample from the patient before exposing it to nitroblue tetrazolium dye. The NBT Test starts with stimulant application either through bacterial agents or chemical substances like phorbol myristate acetate which activates neutrophils to produce superoxide. Under normal immune system conditions, the NBT dye reduces to form a blue-coloured precipitate. Scientific laboratory equipment in conjunction with microscope analysis determines the test results by evaluating the dye's color changes to determine CGD status.
The healthcare professional obtains patient blood which is combined with NBT dye along with stimulant substances for analysis during the NBT Test. The microscopic examination shows blue formazan deposits in the specimen after it experiences incubation time. Neutrophils that reduce NBT dye lead to a positive result in the test which signifies normal immune response function. The absence of color change indicates the patient cannot form reactive oxygen species thereby indicating the presence of CGD.
There are no specific requirements for Nitroblue tetrazolium test preparation but telling your doctor about infections or medications you take helps the physician understand results correctly. You can find more details about the NBT Blood test from any Aster Labs Centre near you.
