Fluoroimmunoassay where detection of the hapten-antibody reaction is based on measurement of the increased polarization of fluorescence-labeled hapten when it is combined with antibody. The assay is very useful for the measurement of small haptenic antigens such as drugs at low concentrations.
Immunologic techniques based on the use of: (1) enzyme-antibody conjugates; (2) enzyme-antigen conjugates; (3) antienzyme antibody followed by its homologous enzyme; or (4) enzyme-antienzyme complexes. These are used histologically for visualizing or labeling tissue specimens.
Detection of drugs that have been abused, overused, or misused, including legal and illegal drugs. Urine screening is the usual method of detection.
Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.
Examination of urine by chemical, physical, or microscopic means. Routine urinalysis usually includes performing chemical screening tests, determining specific gravity, observing any unusual color or odor, screening for bacteriuria, and examining the sediment microscopically.

  • EMIT urine assays for drugs such as cannabinoids, morphine, and amphetamine are designed to detect the drug itself or a metabolite of the drug present in a concentration above a pre-specified minimum detection cutoff limit. (
  • Firstly, most testing labs use the EMIT (Enzyme Multiplied Immunoassay Technique) test. (
  • The EMIT can detect small amounts of drug metabolites (including marijuana) in your urine sample. (
  • This actual drug test is called the GC MS (gas chromatography mass spectrometry) test, and it is much more accurate than the EMIT test. (
  • So, your first priority in any urine test is to pass the EMIT screening, so you ll never be subjected to the GC MS test. (
  • EMIT is the acronym for enzyme multiplied immunoassay technique, the cheapest and most common drug screen used in workplace drug testing. (
  • EMIT testing is typically used by employers as a preliminary drug screen because the test is prone to incorrect results. (
  • Most workplace drug testing programs (including regulations for all US federal jobs) mandate all positive EMIT tests be confirmed by GCMS to eliminate the likelihood of "false positive" test results. (
  • The following analytical techniques outlined in Figure 1 were used: Toxi-lab Thin Layer Chromatography, Gas Liquid Chromatography (NP, EC and FID detection), High performance Liquid Chromatography, Enzyme Multiplied Immunoassay Technique (EMIT) and Gas Chromatography/Mass Spectrometry. (

  • EMIT stands for enzyme multiplied immunoassay technique and involves a urine sample from the subject. (
  • Aspirin is said to work especially well for Enzyme multiplied immunoassay technique, or EMIT, drug tests. (
  • Aspirin is thought to be able to interfere in EMIT testing and mask certain areas of the enzyme testing. (
  • Twenty years ago when drug testing was first becoming common and popular, aspirin may have been an ideal way to try to beat an EMIT drug test. (
  • Today, laboratories and testing facilities have much more advanced techniques that they use for testing other than just the EMIT test. (
  • Although companies can still opt to use the EMIT method for drug testing purposes, they can also ask that other techniques are administered to ensure that no adulteration is being used in trying to pass a drug test. (
  • In the above presentation, my counterpart was the Syva Corporation and its drug-testing method: the Enzyme Multiplied Immunoassay Technique (EMIT) system. (
  • EMIT is a common method for qualitative and quantitative determination of drugs and certain proteins in serum and urine of humans. (
  • One such technique, the enzyme-multiplied immunoassay technique (EMIT), is used by toxicologists because of its speed and high sensitivity for detecting drugs in urine. (
  • In a typical EMIT analysis, antibodies that will bind to a specific drug are added to the subject's urine. (
  • EMIT (Enzyme multiplied immunoassay technique) This is the most widely used test by employers because of its low cost. (
  • Courts have ruled that repetition of the EMIT test does not constitute confirmation of a positive drug finding. (
  • Advil) will not test positive for marijuana on modern drug screens, but numerous OTC cold remedies may trigger "false positive" results for amphetamines, primarily on the EMIT test. (
  • Immunoassays involve the use of immunoglobins (antibodies), and include ELISA (Enzyme-Linked Immunosorbent Assay) and RIA (radio-immunoassay), or EMIT (enzyme-multiplied immunoassay technique). (
  • EMIT is based on competition for an antibody binding between drug in the sample and drug labelled with an enzyme. (
  • A non-competitive version of EMIT has also been developed which utilizes an excess of drug-specific antibody. (
  • Detectability of new psychoactive substances, 'legal highs', in CEDIA, EMIT, and KIMS immunochemical screening assays for drugs of abuse. (
  • Cross-reactivities and structure-reactivity relationships of six benzodiazepines to EMIT(®) immunoassay. (
  • Enzyme-multiplied immunoassay technique (emit) and radioimmunoassay (ria) are routinely encountered, and such values are considered here. (
