Many laboratory tests require serum or plasma for analysis, including comprehensive metabolic panels, liver function tests, and lipid profiles. Serum is obtained by allowing blood to clot and then separating the liquid portion, while plasma is obtained by preventing clotting, often using anticoagulants. These tests assess various biochemical markers in the blood to evaluate organ function, metabolic status, and overall health.

Which laboratory test can detect hypocalcemia?
serum calcium test
What color tube for rapid plasma reagin?
The rapid plasma reagin (RPR) test typically requires a red or gold-topped tube for blood collection. These tubes contain no anticoagulants and are used to obtain serum samples for testing. It's important to follow specific laboratory protocols for accurate testing.
Do you centrifuge blood for a progesterone test?
Yes, blood samples for a progesterone test are typically centrifuged. Centrifugation separates the plasma or serum from the blood cells, which is necessary for accurate hormone level measurement. The resulting serum or plasma is then used for the progesterone assay. It's essential to follow specific laboratory protocols to ensure reliable results.
Why you prefer serum for serological test than plasma?
Serum is preferred over plasma for serological tests because it does not contain anticoagulants. This prevents interference with certain antibodies and ensures accurate test results. Serum is also easier to handle and process compared to plasma.
What tube is used to test cholesterol?
A serum or plasma sample is typically used to test cholesterol levels. The sample is collected in a tube with no anticoagulant or a tube containing a gel separator to separate the serum or plasma from the cellular components after centrifugation.
What blood test has to be put straight in ice?
A blood test that requires plasma or serum should be placed on ice immediately to prevent the sample from clotting. This includes tests like glucose, electrolytes, liver function tests.
Why is serum preferred over plasma in serologic determinations?
serum is the preferred specimen for most chemistry, blood bank and serology test because proteins, such as fibrinogen, cause intererferences in the procedure or test. anticoagulant may also cause interferences which is present in blood plasma.
What is a laboratory test where venous blood is clotted in a test tube?
A laboratory test where venous blood is clotted in a test tube is called a serum clotting test. Once the blood sample clots, it is centrifuged to separate the liquid portion (serum) from the clot, which can then be used for various diagnostic tests.
Do you spin red test tubes?
Yes, red test tubes are often spun in a centrifuge to separate components of blood, such as serum or plasma, from the cellular elements. This process allows for the collection of clear serum for various laboratory tests. It's important to follow specific protocols regarding centrifugation speed and time to ensure optimal separation without damaging the samples.
What color tube for serum iron blood test?
The color tube for a serum iron blood test is typically a gold or red-speckled/gray-stopper tube, which is specifically designed for collecting blood for serum tests. It is important to confirm with the laboratory or healthcare provider regarding the specific tube color and collection instructions for the test.
What is procedure code 82570?
Procedure code 82570 refers to a laboratory test for measuring the level of creatinine in the serum or plasma. This test is often used to assess kidney function and is part of routine metabolic panels. It helps in diagnosing kidney disease and monitoring patients with conditions that may affect kidney health.
What is Serum analysis?
serum is part of blood that is left after blood is clotted. when blood collected in test tube it is the part on top that does not clot, usually has a clear yellowish tint. most laboratory tests are perfomed on serum part of blood. some drs will write serum _____ level on scripts sometimes.
