What Total Protein measures
Total protein measures albumin and the globulins together as one figure, which on its own is a fairly blunt instrument: a normal total can hide a low albumin offset by raised globulins. Its value comes from being paired with a separate albumin measurement, because subtracting one from the other gives the globulin fraction and with it the albumin-globulin ratio. That ratio is what shifts in chronic liver disease, in chronic infection and in conditions that drive immunoglobulin production, often before either individual value leaves its reference interval. The laboratory measures two analytes and reports three numbers, and the third is generally the one that carries the clinical signal.
How Philippine laboratories run it
Philippine laboratories almost always report total protein, albumin and the calculated A/G ratio as a block, and clinicians ask for the ratio by name. Because the globulin figure is calculated rather than measured, there is no separate globulin reagent to order: the supply plan needs total protein and albumin in step with each other, and a laboratory that runs out of one has effectively lost the ratio as well. Framar schedules the two together for that reason. Both are standard components of the routine chemistry panel and of the liver panel.
Analyzers it runs on
Calibrator, controls and companion tests

Storage and handling
Refrigerated and kept closed when off the analyzer.
Buying Total Protein in the Philippines
Total Protein is supplied for the BS-600M, BS-430, BS-360E, BS-240Pro, BS-230 and BA-88A. We deliver it with Multi-Sera Calibrator and Chemistry Control Level 1, because a run held up waiting on a separate order costs the same shift a stock-out does. Delivery is scheduled against your monthly Total Protein count, so the bench is not rationing tests in the last week of the month. How we plan clinical chemistry supply.
Questions about Total Protein
Is there a separate reagent for globulin?
No, and there does not need to be. Globulin is calculated by subtracting the measured albumin from the measured total protein, so the two reagents above produce three reported values between them. This is why total protein and albumin should always be ordered on the same schedule: running out of either one takes the A/G ratio with it.
