Ranges
Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ
Quest Diagnostics, Protein, Total and Protein Electrophoresis, CSF 749
| Population | Interval |
|---|---|
| Protein, Total, CSF, <1 month | 15-100 mg/dL |
| Protein, Total, CSF, 1 month-60 years | 15-45 mg/dL |
| Protein, Total, CSF, >60 years | 15-60 mg/dL |
| Protein, Total, CSF, Prealbumin | 1.3-6.9 % |
| Protein, Total, CSF, Albumin | 51.9-67.8 % |
| Protein, Total, CSF, Alpha-1-Globulin | 1.8-6.5 % |
| Protein, Total, CSF, Alpha-2-Globulin | 4.6-10.8 % |
| Protein, Total, CSF, Beta Globulin | 7.8-18.2 % |
| Protein, Total, CSF, Gamma Globulin | 4.8-17.6 % |
Tests
Check the catalog code, specimen, method and preparation for every test that measures Protein, Total, CSF. Select up to five tests to compare them side by side.

- Method
- Spectrophotometry
- Collection
- A CSF specimen is obtained by spinal tap and should be collected in sterile tubes and submitted to the laboratory as soon as possible. Ordinarily, three samples are collected in sterile tubes, labeled sequentially as N° 1 (chemistry and immunology studies), N° 2 (microbiological examination), and N° 3 (cell count and differential). Tubes must be labeled with the patient's full name, date, time of collection, and with the number indicating the sequence in which the tubes were obtained.

Verify these ranges and sources
We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
