2023年2月28日 · The nitroblue tetrazolium test checks if certain immune system cells can change a colorless chemical called nitroblue tetrazolium (NBT) into a deep blue color.

Nitro blue tetrazolium is a chemical compound composed of two tetrazole moieties. It is used in immunology for sensitive detection of alkaline phosphatase (with BCIP). NBT serves as the oxidant and BCIP is the AP- substrate (and gives also dark blue dye).

Nitroblue tetrazolium test is a blood test that measures the ability of the immune system to convert the colorless nitroblue tetrazolium (NBT) to a deep blue. This test is performed as a screen for chronic granulomatous disease (CGD).

In patients who present with signs and symptoms consistent with CGD, a flow cytometric dihydrorhodamine neutrophil respiratory burst assay is a quick and cost-effective way to evaluate NADPH oxidase function. The purpose of this review is to highlight considerations for and challenges in the diagnosis of CGD.

The Nitroblue Tetrazolium test (NBT test), also known as the NBT assay, is a specialized diagnostic tool used to evaluate the ability of white blood cells to produce an oxidative burst. This test is primarily conducted to diagnose chronic granulomatous disease (CGD), a rare immune system disorder.

The nitroblue tetrazolium test checks if certain immune system cells can change a colorless chemical called nitroblue tetrazolium (NBT) into a deep blue color. A blood sample is needed. The chemical NBT is added to the white blood cells in the lab. The cells are then examined under a microscope to see if the chemical has made them turn blue.

Nitroblue tetrazolium test or NBT test measures ROS generated by both spermatozoa and leukocytes. NBT becomes reduced by free oxygen radicals forming a blue-black compound, formazan. The reaction can be monitored spectrophotometrically or the stained cells can be scored histochemically.
