Why can’t a single blood test show you all the information you need instead of having to take multiple tests for different markers?
In: Biology
Different tests require samples in different conditions. Most Blood Chemistry tests are done on serum which is the liquid fraction of clotted blood so no anticoagulants are used in the containers for those tests. Blood Count tests require whole blood so they are collected using an anticoagulant that binds up the calcium in the sample which is required for clotting. Blood Sugar tests are collected using and anticoagulant that not only binds up calcium but inactivates the enzymes which may alter the sugar levels.
