CSF/serum albumin ratio is a test performed to compare the levels of albumin in the cerebrospinal fluid and the serum. It is useful as a measure of the integrity of the blood–brain barrier . [ 1 ] [ 2 ] [ 3 ]
The CSF/serum glucose ratio, also known as CSF/blood glucose ratio, is a measurement used to compare CSF glucose and blood sugar. Because many bacteria metabolize glucose, and because the blood–brain barrier minimizes transversal, the ratio can be useful in determining whether there is a bacterial infection in the CSF. The normal ratio is 0.6 ...
To translate from mass to molar concentration, the dividend (molar mass and the divisor (1000) in the division change places, or, alternatively, distance to right is changed to distance to left. Substances with a molar mass around 1000g/mol (e.g. thyroxine) are almost vertically aligned in the mass and molar images.
A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).
CSF glucose levels can be useful in distinguishing among causes of meningitis as more than 50% of patients with bacterial meningitis have decreased CSF glucose levels while patients with viral meningitis usually have normal CSF glucose levels. Decrease in glucose levels during a CNS infection is caused due to glycolysis by both white cells and ...
Cell processing for downstream analysis: accurate cell numbers are needed in many tests (PCR, flow cytometry), while some others require high cell viability. Measurement of cell size: in a micrograph, the real cell size can be inferred by scaling it to the width of a hemocytometer square, which is known.
It may also be used to detect the presence of malignant cells in the CSF, as in carcinomatous meningitis or medulloblastoma. CSF containing less than 10 red blood cells (RBCs)/mm 3 constitutes a "negative" tap in the context of a workup for subarachnoid hemorrhage, for example. Taps that are "positive" have an RBC count of 100/mm 3 or more. [9]
Packed red blood cells, also known as packed cells, are red blood cells that have been separated for blood transfusion. [1] The packed cells are typically used in anemia that is either causing symptoms or when the hemoglobin is less than usually 70–80 g/L (7–8 g/dL).
