Protein, Total and Albumin, Plasma
This test reports total protein content and albumin level in a plasma sample, reflecting the amounts of these two protein components present in the blood.
About this test
This test measures total protein and albumin using a plasma sample rather than serum. It reports the amounts of these two protein components present in the blood, along with the related globulin and albumin/globulin (A/G) ratio values.
The sample is a 2 mL plasma specimen, collected in a lithium heparin (green-top) tube, and analyzed for total protein and albumin content. Because it uses plasma, it is a related but separate product from the serum-based Protein, Total and Albumin test, and the two are not interchangeable when a clinician has specified one or the other.

Additional details
What this test looks at
The test reports total protein and albumin content, along with the calculated globulin and albumin/globulin (A/G) ratio, from a plasma sample collected in a lithium heparin (green-top) tube. These values reflect the two main protein components in the blood, and a clinician interprets them together, in context, rather than looking at any single value on its own.
Order online and a physician order is included — no doctor's visit and no insurance needed. Your sample is collected at a Quest Diagnostics patient service center.
Laboratory results should always be interpreted by a licensed clinician who knows your health history. This page is information about a test, not medical advice.
Frequently asked questions
What does this test measure?
It measures total protein and albumin in a plasma sample, along with the related globulin and albumin/globulin (A/G) ratio.
How is the sample collected?
Through a blood draw that collects a 2 mL plasma sample in a lithium heparin (green-top) tube.
Do I need to prepare for this test?
No preparation instructions are listed for this test, though people follow any instructions their ordering clinician provides.
Is this different from the serum-based Protein, Total and Albumin test?
Yes. This version uses a plasma sample rather than serum, and is a separate product from the serum-based test.
What does a Protein, Total and Albumin, Plasma test cost without insurance?
$15. Celio Health's price is a flat cash price and insurance is never billed: the required physician's order is included.
