	Ferret Aleutian Disease Virus Antibody ELISA Test
		The ADV Antibody ELISA Test from Avecon Diagnostics, Inc. is a sensitive, specific Immunoassay for the detection of ferret antibody caused exclusively by exposure to ADV.
		In this test, ADV Antibody in ferret saliva or blood (serum/plasma) irreversibly binds to a single ADV protein (identical to protein from the replicating form of ADV, but non-infectious) coated onto a plastic surface.
		Testing is especially important before attempting to breed, and prior to transferring a ferret from one household to another.

		ELISA is an abbreviation for "enzyme-linked immunosorbent assay."
		The ELISA test involves an enzyme (a protein that catalyzes a biochemical reaction).
		ELISA tests are widely utilized to detect substances that have antigenic properties, primarily proteins (as opposed to small molecules and ions such as glucose and potassium).

	Human Immunodeficiency Virus (HIV) Test
		A human immunodeficiency virus (HIV) test detects antibodies to HIV in the blood.
		This test is more difficult than the ELISA to perform, but it is done to confirm the results of two positive ELISA tests.
		The PCR test is very useful to find a very recent infection, determine if an HIV infection is present when antibody test results were uncertain, and screen blood or organs for HIV before donation.

	ELISA Activity
		Partially purified, inactivated HIV antigens pre-coated onto an ELISA plate
		If the patient is HIV+, then this serum will contain antibodies to HIV, and those antibodies will bind to the HIV antigens on the plate.
		Chromogen or substrate which changes color when cleaved by the enzyme attached to the second antibody.

	ELISA Test
		ELISA tests are generally highly sensitive and specific and compare favorably with other methods used to detect substances in the body, such as radioimmune assay (RIA) tests.
		An HIV ELISA, sometimes called an HIV enzyme immunoassay (EIA) is the first and most basic test to determine if an individual is positive for a selected pathogen, such as HIV.
		The test is performed in a 8 cm x 12 cm plastic plate which contains an 8 x 12 matrix of 96 wells, each of which are about 1 cm high and 0.7 cm in diameter.

	HIV & AIDS - Everybody reacts positive on the ELISA test for HIV
		I ran it using the same test kit reagents that are usually used to run the ELISA test in most clinical laboratories worldwide (1).
		It is accepted worldwide that the ELISA test for HIV detects antibodies against what is known as the Human Immunodeficiency Virus (3-4-5-6).
		In this case, a reactive test could be a measure of the degree of one's exposure to stressor or oxidizing agents (15,16).

	MedlinePlus Medical Encyclopedia: HIV ELISA/western blot
		The HIV ELISA is a screening test for the diagnosis of HIV infection.
		If this test is positive, it must be confirmed with a second test called the Western Blot, which is more specific and will confirm if someone is truly HIV positive (there are other conditions that may inaccurately produce a positive ELISA test result, including lupus, Lyme disease, and syphilis).
		A negative test result is normal. However, early HIV infection (termed acute HIV infection or primary HIV infection) often results in a negative test.

	AIDS Test \| AHealthyMe.com
		Some AIDS tests are used to diagnose patients or confirm a diagnosis; others are used to measure the progression of the disease or the effectiveness of specific treatment regimens.
		In Western blot testing, HIV antigen is purified by electrophoresis (large protein molecules are suspended in a gel and separated from one another by running an electric current through the gel).
		An IFA test detects the presence of HIV antibody in a sample of the patient's serum by mixing HIV antigen with a fluorescent chemical, adding the blood sample, and observing the reaction under a microscope with ultraviolet light.

	Everybody reacts positive on the ELISA test for HIV
		The ELISA test is a test for antibodies against what is supposed to be the Human Immunodeficiency Virus or HIV.
		To run this test, an individual's serum has to be diluted to a ratio of 1:400 with a special specimen diluent.
		However, to try to prevent false positive reactions some serologic tests use diluted serum; for example this is the case with tests that look for antibodies to measles, varicelia and mumps viruses which use a dilution of 1:16, to cytomegalovirus [CMV] 1:20 and to Epstein-Barr Virus [EBV] 1:10.

	b) Everybody reacts positive on the ELISA tests for HIV
		For example, the tests that look for antibodies to hepatitis A and B viruses, rubella virus, syphilis, hystoplasma and cryptococus, to mention a few of them, use straight serum [undiluted].
		However, to try to prevent false positive reactions some serologic tests use diluted serum; for example this is the case with tests that look for antibodies to measles, varicella and mumps viruses which use a dilution of 1:16, to cytomegalovirus [CMV] 1:20 and to Epstein-Barr Virus [EBV] 1:10.
		What I noticed is that the absorbance values of the specimens that tested negative when diluted [1:400], but positive when undiluted [1:1], had lower values that the samples that, diluted, react positive on both the ELISA and Western blot tests.

	SF AIDS Fdn: HIV Testing
		Beyond the "window period," ELISA tests are very rarely "false negative." This means if you have a negative test result, and you were tested at least six months after the last potential exposure, you are really HIV negative.
		You may be anxious to be tested soon after an encounter which you perceive to be risky (for a discussion of what behaviors put you at risk for HIV and which ones do not, see the section on How HIV Is Spread).
		Those who are tested confidentially and are found to be infected with HIV are reported to local public health officials so that the government can better track the extent of the disease in the population as a whole.

		The saliva samples were tested by the adjusted rapid ELISA test which is contained in the HIVhometest test kits.
		Of the 368 positives with the HIVhometest, 367 were positive with ELISA test on the serum and 365 were positive with confirmation tests using Western Blot.
		It must be noted that there were not any tests performed at a later date to determine if any of the negative subjects were tested during a time when the disease did not produce sufficient antibodies to be detected.

	s020506a - HIV ELISA Test - False Negative Results
		The first patient, probably infected recently when first tested, was strongly positive by the same assay a year later, confirming the relative insensitivity of oligopeptide assays reported previously for detecting the early antibody response.
		In a total of 13 104 tests there were eight false negative results attributable to assay insensitivity: three were on two serum samples collected close to seroconverison and five on another serum specimen.
		It is essential that the producers of the ELISA test kits use control systems which guarantee sufficient antigen coating.

	CWD Testing Controversy: WVDL IDEXX Elisa CWD test
		An article on Wisconsin CWD test results by Associated Press reporter, Robert Imrie, has brought to light concerns over test procedures, test accuracy, and the reliability of test information released to hunters and the general public.
		Because the older IHC test did not confirm those positive results, the protocol followed by the agency and its testing lab (WVDL) determined that the IDEXX test results were false.
		This low correlation between the two tests flies in the face of the results of the USDA trials of the test that showed almost 100% agreement between the two tests.

	Antibody Tests (ELISA, Western Blot)
		ELISA is not a Yes/No test, it is only a continuum of color change that is interpreted in this way because of an arbitrary cutoff point.
		However, when the ELISA is used to screen populations with a low prevalence of HIV infections, nonspecific reactions may be more common than specific reaction…Specimens found repeatedly reactive by ELISA and positive by additional, more specific tests are considered positive for antibodies to HIV-1.
		Serological tests in accordance with French law were done at the time of the accident and in the 3rd and 6th month afterwards…She had no personal risk factors for HIV infection, and no at-risk circumstances between the accident and the diagnosis of HIV infection.
