The cold agglutinins test is used to confirm the diagnosis of certain diseases that stimulate the body to produce cold agglutinins
The febrile agglutinins test is used to confirm the diagonsis of certain infectious diseases that stimulate the body to produce febrile 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
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.
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.
A cold agglutinins test requires special handling to prevent false results due to temperature sensitivity. Blood samples should be collected in a warm tube and kept at body temperature until they are processed, typically by using a heat block or incubator. Additionally, the sample should be tested promptly, ideally within a few hours, to minimize the effects of cold exposure that can lead to agglutination inappropriately. Proper labeling and immediate transport to the lab are also essential to ensure accurate results.

The ice blood test, commonly known as the cold agglutinin test, is a diagnostic procedure used to detect the presence of cold agglutinins in the blood, which are antibodies that cause red blood cells to clump together at lower temperatures. This test is often used to diagnose conditions like cold agglutinin disease or certain types of autoimmune hemolytic anemia. Blood samples are typically kept on ice before testing to prevent agglutination at room temperature, ensuring accurate results.
Anything that has ephedrine or psuedoephedrine will cause a false screening positive, but there are no cold medications that will confirm positive for methamphetamine.

A blood test for Bartonella henselae may be ordered to confirm the doctor's diagnosis.
