Want this question answered?
A grease spot test will show positive for milk (whole milk, 2% and even slightly for 0% fat) because milk contains animal fats. Even when a process has removed partially or supposedly all of the fats, the grease spot test normally will indicate fats in milk.
In grease spot tests, the filter paper becomes translucent because the substance tested contains lipids.
It depends on what coats the paper, but my guess is that the coat would prevent the lipid from absorbing into the paper. For a lipid test to work, the lipid has to be absorbed to determine if the paper becomes translucent.
Paper Bag test :D
There are none.

No, a grease spot test or Sudan IV test can be used to test for lipids. Ninhydrin is used to test for amino acids.
Patients who are scheduled for a lipid profile test should fast

for me, i think the uncoated paper test is more sensitive than Sudan iv test. This is because Sudan iv test can only soluble in certain solvent thus make it harder to define either the solution that is tested is really have lipid in it although there is not. The uncoated paper test can show if there is lipid the the solution if greasy transparent spot comes out from the uncoated paper.

A lipid panel blood test measures fat substances in the blood. This test can determine the amount of good and bad cholesterol in the blood.
The benzidine test is a test for cyanide. The limitations of this test are that benzidine has been linked to bladder and pancreatic cancer.
