Aflatoxin M 1 may be found in milk, including human milk. In cows, sheep, goats and buffaloes that have consumed feeds contaminated with aflatoxin B 1, aflatoxin M 1 will be formed as a result of the metabolic process in the livers of ruminants and excreted in their milk. Humans can be exposed to the toxins through consumption of contaminated ...
Aflatoxin G 1 and G 2 (AFG), produced by some Group II A. flavus and Aspergillus parasiticus [19] Aflatoxin M 1 (AFM 1), metabolite of aflatoxin B 1 in humans and animals (exposure in ng levels may come from a mother's milk) Aflatoxin M 2, metabolite of aflatoxin B 2 in milk of cattle fed on contaminated foods [20]
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
A multiplex assay is a derivative of an ELISA using beads for binding the capture antibody. Multiplex assays are still more common in research than in clinical settings. [2] In a multiplex assay, microspheres of designated colors are coated with antibodies of defined binding specificities.
Aflatoxin B 1 is an aflatoxin produced by Aspergillus flavus and A. parasiticus. It is a very potent carcinogen with a TD 50 3.2 μg/kg/day in rats. [ 4 ] This carcinogenic potency varies across species with some, such as rats and monkeys, seemingly much more susceptible than others.
The setting of reasonable cutoff limits help reduce false positive results that occur from assay limitations. Because of the social and legal consequences, a positive test result must be confirmed by an alternative method, usually Gas Chromatography/Mass spectrometry.
An important practical relevance of the phenomenon is as a type of interference that plagues certain immunoassays and nephelometric assays, resulting in false negatives or inaccurately low results. Other common forms of interference include antibody interference, cross-reactivity and signal interference.
A NASA illustration of a lateral flow assay. A lateral flow test (LFT), [1] is an assay also known as a lateral flow immunochromatographic test (ICT), or rapid test.It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment.
