Web28 aug. 2024 · What Biological Half-Life Means. No drug stays in your system forever. In pharmacology, the time it takes for a drug to decrease by half its plasma (blood) concentration is called its half-life (t1⁄2). (Specifying that we're talking about biological half-life is key because the half-life is a concept not specific to medicine. WebHemoglobin is a protein that carries oxygen from the lungs to other parts of the body and carries carbon dioxide back to the lungs. But it binds more tightly to carbon monoxide, making COHb a useful biomarker of exposure to carbon monoxide. ... The HPHCs selected for measurement vary in their elimination half-life times, ...
