LOINC short name : RBC tube4 # CSF Manual;
LOINC description : A sample of cerebrospinal fluid (CSF) is collected using a procedure called a lumbar
puncture or spinal tap. Often, three or more separate tubes of CSF are collected (tube
1, tube 2, tube 3), and multiple tests may be run on the different tubes. Normally
no erythrocytes are present in CSF. The presence of red blood cells may indicate bleeding
into the CSF or may indicate a traumatic tap - blood that leaked into the CSF sample
during collection. [Lab Tests Online];
