Why RPR test not perform by csf?
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.

Why does a colloid appear cloudy?
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."

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.
