Prothrombin is a plasma protein that is involved in the clotting process of blood. Its normal concentration in plasma is 30mg/200ml. What percent of the plasma is prothrombin?.
Given what we know, we can confirm that Prothrombin circulates through the blood at a percentage of about 15%.
How do we reach this percentage value?In order to reach this value, analysis of blood samples have shown the exact amounts that circulate per every set amount of blood, we can then divide these values in order to get a decimal value for the percentage, which after converting leads us to the answer of about 15%.
Therefore, we can confirm that Prothrombin circulates through the blood at a percentage of about 15%.
