Why take a PT and PTT with INR test? The Prothrombin Time (PT/INR) and Partial Thromboplastin Time (PTT) test is used to measure how long it takes the blood to clot. These two tests, combined, are needed to initiate an investigation when there is unexplained bleeding or clotting. It clarifies the cause.

Plasma protein tests are blood tests that detect the amount of proteins in the blood. This lab work is usually ordered as part of a comprehensive metabolic panel (CMP) during a physical exam. The tests can help your doctor determine your overall health. Plasma protein tests are also known as a total protein test.

A: A Reporting Limit (RL or RDL) is the limit of detection for a specific target analyte for a specific sample after any adjustments have been made for dilutions or percent moisture. ... In contrast, the Method Detection Limit or MDL is lower than the RL (often much lower) and is a statistical calculation.
