What is the live blood test analyzer?(2)


In order to best understand the difference and the benefits of this particular test it is necessary to consider the conventional blood test that is given at the doctor’s surgery or hospital, known as a Complete Blood Count (CBC). Almost every person has experienced this particular test which involves inserting a needle into the patient’s arm and extracting a syringe full of blood, which can be a very painful ordeal for some people. The blood sample is then sent to a laboratory to be examined by a haematologist and it can take up to two weeks to receive the results. 
However, the major problem with this test is that half an hour after the blood cells are extracted from the human body they die so the haematologist is merely counting dead blood cells. The blood is also changed through the addition of stains and dyes in order to facilitate the analysis. The results take the form of a quantitative analysis of the blood, that is to say how many dead red blood cells, how many dead white blood cells, what number is the cholesterol level etc.
Above these , we can know , in some way , live blood test have a big advantage when we do some blood test for sick diagnosis by hematology analyzer or other medical analyzer. The live blood can tell us more information better then regular blood test.
