A confirmatory test establishes the accuracy or correctness of another procedure.
There are several different ways to confirm HIV infection. One of the most common confirmatory testing methods is by Western Blot. There is also a confirmatory test called ELISA.
The confirmatory test for oxalate is the alkaline permanganate test. In this test, a sample containing oxalate ions is treated with potassium permanganate in a basic solution. The formation of a pink color indicates the presence of oxalate ions.
The confirmatory test for casein involves performing a specific protein test, such as a Bradford assay, to detect the presence of casein. This test helps confirm the presence of casein in a sample, particularly in food products or biological samples.
it is more accurate
Its Flame Test:it gives golden yellow colour to non luminous flame which is not seen through a blue glass.
A confirmatory test for ketones is a urine test using ketone test strips. These strips contain a chemical that reacts with the ketones in urine, changing color to indicate the presence and degree of ketonuria. This test helps to diagnose and monitor conditions such as diabetic ketoacidosis or ketosis.
A confirmatory test for blood is DNA analysis. This test can definitively identify the source of the blood sample by comparing its genetic profile to that of a known individual. It is highly accurate and is often used in forensic investigations or paternity testing to provide conclusive evidence.
A good confirmatory test for fat is Sudan III test. Take a test sample and add a few drops of Sudan III. A red stain shows that fat is present. Paper test is another test for fat. Melt the fat and drop it on a piece of paper. If it forms a translucent grease spot, fat is present.
The first test performed is ELISA (or EIA) is a test that screens for the presence of HIV antibodies in the blood. This test is not a test for HIV/AIDS its a very sensitive and will be reactive even if there are only 1 or 2 antibodies in that person blood sample. If the results are reactive that test will be followed by a second test called confirmatory test which is highly accurate test in which it's is used to confirm the results of the ELISA.
The confirmatory test for the nitrite anion involves the Griess test, which detects the presence of nitrite ions in a sample by forming a deep red color complex with sulfanilic acid and N-(1-naphthyl)ethylenediamine dihydrochloride. This test is commonly used in the detection of nitrite in water, food, and biological samples.
