There is a bedside version of the test in which the doctor collects four or five drops of blood in a small tube, cools the tube in ice water for 30-60 seconds, and looks for clumping of red blood cells.
The cold agglutinins test is performed to detect the presence of antibodies in blood that are sensitive to temperature changes.

Your local building department and the Plumbing Code, a normal test for a water system is to prime the system at the pressure it will be running, as long as it's not above 80psi and checking for visible leaks and pressure drop or meter movement.
A cold conductor is the insilation for a cold object to keep the coolness inside and the warmess out.
The cold agglutinins test is used to confirm the diagnosis of certain diseases that stimulate the body to produce cold agglutinins
The results of the cold agglutinins test require a doctor's interpretation. In general, however, a normal value is lower than 1:32.
disease most commonly diagnosed by this test is mycoplasmal pneumonia, but mononucleosis, mumps, measles, scarlet fever, some parasitic infections, cirrhosis of the liver, and some types of hemolytic anemia can also cause the formation of cold agglutinins
The febrile agglutinins test is used to confirm the diagonsis of certain infectious diseases that stimulate the body to produce febrile agglutinins.
Any value higher than 1:32 suggests a diagnosis of mycoplasmal pneumonia or one of the other viral infections or disease conditions indicated by this test.

DefinitionAgglutinins are antibodies that cause the red blood cells to clump together.Cold agglutinins are active at cold temperatures.Febrile (warm) agglutinins are active at normal body temperatures.This article discusses the blood test used to measure the level of these antibodies in the blood.Alternative NamesCold agglutinins; Weil-Felix reaction; Widal's test; Warm agglutininsHow the test is performedBlood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. (The tube is first warmed to normal body temperature - 98.6 degrees F). The elastic band is removed from your arm.Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.The sample is sent to a laboratory.How to prepare for the testThere is no special preparation.How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedThis test is done to diagnose certain infections and to determine the cause of hemolytic anemia. Distinguishing between warm and cold agglutinins can help understand why the hemolytic anemia is occurring and can direct therapy.Normal ValuesWarm agglutinins: no agglutination in titers at or below 1:80Cold agglutinins: no agglutination in titers at or below 1:16Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanThe presence of warm agglutinins may occur with:Infections, including brucellosis, rickettsial disease, salmonella infection, and tularemiaLymphomaSystemic lupus erythematosusUse of certain medicines, including methyldopa, penicillin, and quinidineThe presence of cold agglutinins may occur with:Infections, especially Mycoplasma pneumoniaPrevious viral, staphylococcal, or malaria infectionCancer, including lymphoma and multiple myelomaSystemic lupus erythematosusWhat the risks areVeins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.Other risks associated with having blood drawn are slight but may include:Excessive bleedingFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)Special considerationsIf cold agglutinin disease is suspected, the individual needs to be kept warm.ReferencesSchwartz RS.
