How to detect iodide ions? Mercuric chloride test is considered as a specific test for detection of the presence of iodide ion as the acid radical of a salt. The test depends on adding mercuric chloride on a potassium iodide solution which results in formation of a reddish precipitate of mercuric iodide.
How do you test for iodine in chemistry? Starch Test: Add Iodine-KI reagent to a solution or directly on a potato or other materials such as bread, crackers, or flour. A blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow.
How is serum cytokine measured? The enzyme-linked immunosorbent assay (ELISA) is a routine method for analysis and measurement of secreted cytokines. This assay is classically designed for the analysis of one analyte at a time and, therefore, has a low throughput [54].
Can cytokines be detected in blood test? Cytokines have not been employed in clinical laboratory tests because of the many biological activities of individual cytokines and too complicated cytokine network. However, abnormal laboratory data and symptoms can be interpreted by blood cytokine levels.

How early can a sonogram detect a pregnancy?
In viable pregnancies, trans-vaginal (internal) scans should be able to detect a gestation sac from 5 weeks of pregnancy. A yolk sac can be seen at 5 1/2 weeks gestation. Trans-abdominal (external) scan may be less accurate at this early 5 week stage.

Summary. A method based upon Marsh-Berzelius’ arsenic mirror test has been developed for the determination of arsenic in biological material. The arsenic mirror is dissolved in a hypobromite solution and the arsenic is determined colorimetrically by a heteropoly blue method.
Can endometrial cancer be detected by Pap smear?
