What does AG mean in a blood test?
In a blood test, "AG" typically refers to "antigen," which is a substance that can trigger an immune response. Antigens are often used in tests to detect infections, autoimmune diseases, or other health conditions. For example, specific antigen tests can identify the presence of viruses or bacteria in the body. Additionally, "AG" can also refer to "albumin/globulin ratio," an important marker in assessing liver and kidney function.
What is the purpose of m9 paper?
Chemical Agent Detector Paper, M9 is the most widely used method of detecting liquid chemical warfare agents, such as nerve or blister agents. M9 Paper reacts to chemical agents by turning a red or reddish brown color. It will not detect vapor.
What substance used to detect the presence of carbon dioxide?
Test for Carbon Dioxide: Bubble unknown gas in lime water. Limewater should go milky if Carbon dioxide is present. Test for water: Add anhydrous copper sulphate crystals (white in colour) to unknown solution. If solution goes a brilliant light blue colour, water is present as the hydrous copper sulphate crystals were formed. Did this help?
What type of substance is litmus?
Litmus is used to indicate the either the chemical to be used is acid or a base. so the substances that change colour like litmus are called INDICATORS. Methyl orange and phenolphthalein is also an indicator.
What does emulsion test detect?
The emulsion test is used to detect the presence of lipids (fats) in a substance. It involves mixing the test substance with ethanol and water to form an emulsion. The presence of a white emulsion indicates the presence of lipids.
What is an indicator used to detect an acid or base?
An indicator used to detect an acid or base is a substance that changes color in the presence of acids or bases. Examples of indicators include litmus paper, phenolphthalein, and universal indicator solution.
What is a man made indicator?
A man-made indicator is a substance that changes color in the presence of a specific condition or substance. It is commonly used in laboratory settings to visually detect the presence of acids, bases, or other chemical reactions. Examples include litmus paper, phenolphthalein, and bromothymol blue.
What test can be used to detect substance of emulsion?
A drop test can be used to detect the presence of an emulsion. Add a drop of the emulsion to water. If it disperses or forms a milky appearance, it indicates the presence of an emulsion.
What test can be use to detect the presence of glycine?
fischer's method, zimmerman and klein and linser
What is used to detect the presence of an acid or alkali?
A universal indicator is commonly used to detect the presence of an acid or alkali. It changes color based on the acidity or alkalinity of a solution, helping to identify whether a substance is acidic, neutral, or alkaline.
What turns color in the presence of strach?
In the presence of starch, iodine turns purple.
Why can phosphorus-32 be used to detect the presence of nucleic acids but not amino acids?
amino acids only contain carbon,hydrogen,oxygen and nitrogen. they do not contain phosphorus and cannot be incorporated. the ion phosphoric acid is found in nucleic acid.
What is iodine in the presence of when it turns black?
When iodine turns black, it is usually in the presence of starch. This forms a blue-black complex that is used in various chemical tests to detect the presence of starch in a substance.
What is the gas produced when any metal reacts with acids?
Hydrogen gas is produced when any metal reacts with acids. This is a common reaction that is often used to test for the presence of metal in a substance.
A substance used to detect or measure another substance or to convert a substance into another?
a reagent
Is Ninhydrin used to test for the presence of lipids?
No, Ninhydrin is not used to test for the presence of lipids. Ninhydrin is commonly used to detect the presence of amino acids or proteins by producing a purple color when in contact with them. Lipids are usually tested using methods like the Sudan Red test or the paper towel test.
