Vinegar test dry ice. Vinegar highlights tumors, which have more DNA, and therefore less water and more protein, than healthy tissue. As of 2011, Thailand has adopted the technique in twenty-nine of its (then) seventy-five provinces, and 500,000 women have been tested at least once. The vinegar test does have important limitations and disadvantages for cervical cancer screening, as well; please refer to that section in the main Cervical_screening article. Vinegar test Vinegar test is a cervical cancer testing method that uses acetic acid, a major component of vinegar. It has been found to be useful as an effective and inexpensive screening
Glutaconic acid can be used to make it: the "trans" form isomerizes under the reaction conditions. Glutaric, 3-hydroxyglutaric, and glutaconic acids are structurally related metabolites. In glutaric aciduria type 1, glutaconic acid accumulates, resulting in brain damage. Glutaconic acid "trans"-Glutaconic acid is an organic compound with formula HOCCH=CHCHCOH. This dicarboxylic acid exists as a colorless solid and is related to the saturated chemical glutaric acid, HOCC(CH)COH. Esters and salts of glutaconic acid are called glutaconates. The geometric isomer, "cis"-glutaconic acid, has a noticeably lower melting point (130–132 °C). It can be prepared by bromination of levulinic acid followed by treatment of the
