What is the confirmatory test for oxalate?
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.
What is the confirmatory test for casein?
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.
Why dry test isn't considered as confirmatory test?
A dry test isn't considered a confirmatory test because it typically lacks the sensitivity and specificity required to definitively identify a substance or condition. Unlike confirmatory tests, which are designed to provide clear and reliable results through rigorous methodologies, dry tests may produce false positives or negatives. Additionally, dry tests often measure only qualitative results rather than quantitative data, limiting their reliability in making definitive conclusions. Therefore, while they can be useful for preliminary screening, they cannot replace more rigorous confirmatory testing methods.
What color does sodium hydroxide burn in a flame test?
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/
What element Produces a yellow flame test barium or sodium?
Sodium produces a yellow flame test. When sodium compounds are heated, they emit a bright yellow light due to the excitation of sodium ions. Barium, on the other hand, produces a green flame when tested. Thus, in a flame test, the yellow flame is characteristic of sodium.

What is the clinical benefit of completing the Western Blot as a confirmatory test for the ELISA test?
it is more accurate
What is a confirmatory test for ketones?
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.
What is a confirmatory test for blood?
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.
What is the confirmatory test for fat?
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.
What is the confirmatory test or nitrite anion?
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.
