Serum because it has no fibrinogen or it has no clotting factors.
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.
The RPR (Rapid Plasma Reagin) test is a non-treponemal test used to screen for syphilis, primarily using serum rather than cerebrospinal fluid (CSF). This is because RPR detects antibodies that are typically present in the bloodstream, as they are produced in response to the infection. While CSF analysis can be useful in diagnosing neurosyphilis, RPR is not performed on CSF due to its higher sensitivity and specificity when using serum, and the complexity involved in CSF collection and analysis.
Kirby-Bauer method (uses disk diffusion method)E-test (uses capillary disks)Spiral Gradient Endpoint test (results are interpreted by computer)Serum Bactericidal test (test amount of antibody present in patient's serum)
The cloudier your plasma is, the more platelets it has.I have not found any reference to the amount of platelets and plasma turbidity. Please see next answer..."Turbid, cloudy or milky serum (lipemic serum) may be produced by the presence of fatty substances (lipids) in the blood. Bacterial contamination may also cause cloudy serum. Moderately or grossly lipemic specimens may alter certain test results.A recent meal may produce transient lipemia; therefore, we recommend that patients fast 12-16 hours before a blood specimen is obtained."
Venous blood clotted in a test tube is called a serum sample. Serum is the liquid component of the blood that remains after blood clots and is used for various diagnostic tests.
Icterus, Hemolysis, or Lipemia interfere with reading the color change
Widal test is a serological test used to detect enteric fever by using agglutination rection of antibodies present in the serum of typhoid patient and o-somatic and H-flgellar antigens.
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.
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.

Blood test
how can you test for any toxity in blood serum or serum tears.
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.
A red top tube is typically used for a rapid plasma reagin (RPR) test, which is a screening test for syphilis. The red top tube contains no anticoagulant and allows for blood to clot before the serum is separated for testing.
Blood glucose tests require either whole blood, serum, or plasma collected by vein puncture or finger puncture. No special preparation is required for a casual blood glucose test.
