Enzyme Multiplied Immunoassay Technique

The Enzyme Multiplied Immunoassay Technique, or EMIT, is a common method for screening urine and blood for drugs, whether legal or illicit. It is part of the homogeneous immunoassay.

The technique is relatively nonspecific compared to some other analysis methods, such as mass spectrometry, but has the advantage of being fast and inexpensive. It has, however, been shown in some cases to be somewhat inaccurate in its findings. The patent for EMIT technology is owned by the Syva Corporation of Palo Alto, CA.

In March of 2005, the patent for EMIT technology was sold for an undislosed price to the ORAK Corp, which is based in San Francisco.
