First section: Blood routine test (BRT) Has Someone here ever heard of BRT before? Yes! Very good many students have heard before. (NO? maybe you are all very healthy ).when you go to hospital, doctors always apply for a BRT as a reference to your disease. They can know about the red blood cells ,white blood cells and platelets et,al. So BRT is the most common examination in clinical laboratory. Today we will learn the blood routine test (the abbreviation is BRT) or complete blood count (CBC). 1．Sample collecting first, we will learn about the collection of BRT sample. The blood can be collected from finger or vein. But we are always collecting blood from vein, Because the result come from a vein sample is more accurate and stable than from finger. But if it is very difficult to find a good vein to collect, for example ,when we meet with a baby. After we collected the sample, the blood must be anticoagulated with EDTA-K 2. Because we will count cells in it. We will learn in the later. Here please remember the anticoagulantEDTA-K2. OK, lets take a look of the main contents of BRT. It conclude three parts, they are RBC,WBC,PLT. Now we will learn one by one. 2. RBC related parameters At first, will learn about the red blood cells. There are seven parameters related to it. They are： The number of red blood cells (RBC) The amount of hemoglobin in the blood (Hb) Hematocrit （Hct） mean corpuscular volume (MCV) Mean corpuscular hemoglobin（MCH） Mean corpuscular hemoglobin concentration (MCHC) Red blood cell volume distribution width（RDW) RBC and Hb Now ,lets learn about RBC and hemoglobin. we put the two indexes together ,because they have the same clinical signifcance. （1）The normal values The normal values of RBC is to male :the normal number of RBC is 4.0-5.5,to Female: is 3.5-5.0 million millions per liter . so it is different between male and female. Familiar to RBC, the normal value of hemoglobin is different between male and female too. All the values
