As a safety precaution, researchers assess the blood platelet counts of trial participants frequently. This results in a platelet count result which is lower than it actually is. a. Hb (Hemoglobin): Hb amount indicates how much blood Contains Hb. Transfusions will be immediately ordered if this is the test result.
