Chemical test

In chemistry, a chemical test is qualitative or quantitative procedure designed to prove the existence of, or to quantify, a chemical compound or chemical group with the aid of a specific reagent. A presumptive test is specifically used in medical science.

Biochemical tests

 * Clinistrips quantitatively test for sugar in urine
 * The Kastle-Meyer test tests for the presence of blood
 * Salicylate testing is a category of drug testing that is focused on detecting salicylates such as acetysalicylic acid for either biochemical or medical purposes.
 * Iodine solution tests for starch
 * The Van Slyke determination tests for specific amino acids
 * The Zimmermann test for Ketosteroids
 * Seliwanoff's_test for differentiating between aldose and ketose sugars
 * Test for fat: add ethanol to sample, then shake; add water to the solution, and shake again. If fat is present, the product turns MILKY WHITE.

Reducing sugars

 * Barfoed's test tests for reducing monosaccharides or disaccharides
 * Benedict's reagent tests for reducing sugars or aldehydes
 * Fehling's solution tests for reducing sugars or aldehydes, similar to Benedict's reagent
 * Molisch's test for carbohydrates

Proteins and polypeptides

 * The Bicinchoninic acid assay tests for proteins
 * Biuret reagent tests for proteins and polypeptides
 * Bradford protein assay measures protein quantitatively

Organic tests

 * The Carbylamine reaction tests for primary amines
 * The Griess test tests for organic nitrite compounds
 * The Iodoform reaction tests for the presence of methyl ketones, or compounds which can be oxidized to methyl ketones
 * The Schiff test detects aldehydes
 * Tollens' reagent (Silver Mirror) tests for aldehydes
 * The Zeisel determination tests for the presence of esters or ethers
 * Lucas' reagent is used to determine mainly between primary, secondary and teriary alcohols.

Inorganic tests

 * Barium chloride tests for sulfates
 * The Beilstein test tests for halides qualitatively
 * Borax bead test tests for certain metals
 * The Carius halogen method measures halides quantitatively
 * Chemical test for cyanide tests for the presence of cyanide, CN-
 * Copper sulfate tests for presence of water
 * Flame tests test for metals
 * The Gilman test tests for the presence of a Grignard reagent
 * The Kjeldahl method quantitatively determines the presence of nitrogen
 * Nessler's reagent tests for the presence of ammonia
 * Ninhydrin tests for ammonia or primary amines
 * The sodium fusion test tests for the presence of nitrogen, sulfur, and halides in a sample
 * The Zerewitinoff determination tests for any acidic hydrogen
