| name | Erythrocytes [#/volume] in Cerebral spinal fluid by Manual count --3rd tube | ||
| 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] | ||

| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
