Other tests that are useful in determining the extent of CO poisoning include measurement of other arterial blood gases and pH; a complete blood count.
Iodine tests for the presence of starch. It is brownish yellow in color if there is no starch present, and bluish black if starch is present. Benedict's solution is used to test for the presence of a reducing sugar, changing from its usual color blue to green to brick red if reducing sugars are present. No reducing sugar solution stays blue.
According to our chemistry lab "post lab", AgNO₃ served as a catalyst; tests the presence of Chloride ion.
Carbon and hydrogen are detected qualitatively by heating a mixture of the given substance with dry copper (II) oxide in a glass tube. The organic substance is oxidize and carbon dioxide and water are formed. The presence of carbon dioxide is indicated by the formation of a white precipitate of calcium carbonate, when the gaseous products are passed through a solution of lime water. The presence of hydrogen is indicated by the formation of droplets of water in the tube.
an analyst who tests minerals is called a ?
Streak is one of the most useful tests
There are basically two types of smoke detector; one type measures the opacity of the air to literally "see" if there is smoke. The other type tests for ionization that occurs when there is a fire. That type smoke detector uses a small radioactive chip to determine if freshly ionized smoke is present. It's a far more accurate means of determining the presence of fire and associated hazardous smoke. Many smoke detectors use a combination of both detectors. A separate type of detector is the carbon monoxide detector, which senses the presence of harmful carbon monoxide in the air. Most will even indicate the percentage of carbon monoxide. Note that carbon monoxide is typically present when a furnace or other heating device malfunctions.

Yes, a test strip is available that determines whether there is carbon monoxide in the coolant. If a headgasket is leaking the carbon monoxide from the combustion process will build up in the coolant. That simple test will determine if the head gasket is leaking.
Sudan tests for the presence of lipids ;D
KOH Prep and wet prep are both tests in microbiology. The KOH prep tests for fungal elements and yeast. The wet prep tests for yeast, tricomonas (a sexually transmitted parasite), and clue cells (which indicate the presence of a bacterial infection).
blood clotting
To test for iron in the food, crush the food into small pieces. If the pieces travel towards a magnet, they have iron in them.
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.
It tests for the presence of starches in an organic compound..
In schools, these are called Presidential Fitness Tests.
These tests are performed to determine the carbon-sulfur content of some metals. Certain metals comply to a specific standard due to the levels of its carbon-sulfur content.
Blood tests are used to measure the amounts of certain protein markers, such as prostate-specific antigen (PSA), found circulating in the blood.
