What do scientists use qualitative analysis for?
Qualitative analysis means "finding out what's in the beaker of stuff there". Scientists use it to find out exactly what is in a solution or sample, in order to confirm the presence or nonpresence of a specific chemical or ion, and to find out how to proceed with other tests.
What organic molecule does iodine test for?
They test for carbohydrates. The Iodine reagent tests for starch. The Benedict's reagent tests for small sugars. Most carbohydrates are are made of sugar, and starch is a type of carbohydrate.
Tests for what chemicals will indicate that the liver is not functioning properly?
Tests that can indicate liver dysfunction include liver function tests (LFTs) such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), which measure liver enzyme levels. High levels of these enzymes can indicate liver damage. Other tests include bilirubin levels, which can indicate impaired liver function, and prothrombin time (PT), which measures the liver's ability to produce clotting factors.
What do activators do?
They help the blood sample in the tube clot so that serum can be separated for analysis. Serum is the preferred specimen for many tests such as hormones, proteins and electrolytes.
What is the I2KI used for?
It is used to test for the presence of starch in substances.
How do you test for each type of organic molecule in foods?
The Qualitative tests for each of the macronutrients are as follows: Carbohydrates - Iodine test and/or Benedicts test Proteins - Biuret test Fats - Ethanol (Emulsion) test
What is the importance of Molisch's test performed on carbohydrates?
Molisch's Test is a chemical test for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid to produce an aldehyde. Its importance is that it tests the presence of carbohydrates based on their dehydration,

What is the difference between a qualitative and a quantitative assay?
In assays, or medical tests, both qualitative and quantitative tests occur. The qualitative test identifies the presence or absence of the pathogen or toxin (or other molecule) being tested for, while the quantitative test hopes to measure how much of that particular substance is in the body.
What is the use of the tests for proteins?

Are pregnancy tests the same as drug tests?
Pregnancy tests detect certain chemicals in a woman's urine which are otherwise not present if not pregnant. Otherwise NO.
Is a blood test accurate to know if you are pregnant?
Normally, yes. But qualitative blood tests (yes/no) have more cases of error than quantitative tests (done days apart).
Do proteins give positive iodine tests?
