The benefits of the Keeping in mind the state of health of the body. And the risk of disease. This is helpful in the prevention and treatment of various diseases such as blood test to diagnose. To find abnormalities early to be useful for prevention. And keeping abreast of the disease.
Collection of blood to The blood drawn from a vein in the arm or wrist. The amount of 2.5 - 3 ml blood collection tubes containing the anticoagulant called EDTA (EDTA) as appropriate ratio. To prevent blood clotting to check.
How the CBC are:
1. How to check the blood slides. And light microscopy And blood some spin to the blood concentration (volume packed cell) of the white blood cells are taken through the process destroys red blood cells and then put the slide and endoscopy to count white blood count again. one
The advantage to this method is a conventional method, of course, is well established in the medical world.
The downside is the need to take on a lot. For example, in the annual health check as a group can not be done because it takes quite a lot to do with the profile. Require personnel with expertise. Physicians diagnose some diseases require hematology.
2. Check with approximately A method that uses the same principles as the first. But cutting step down and take a spin through the blood, the blood concentration. And view the slides The amount of white blood cells, it will estimate the amount of hemoglobin and other airports can not detect it.
The only positive is the cost savings.
The downside can be a diagnostic or screening. If you miss a chance and a lot more. And there is no evidence that is accepted in the medical community.
3. Check with Fully automatic blood analyzer, a technology developed for the CBC in a big hospital. A blood sample to check it.
The advantage is fast and within one minute the result was definitely a little more, using the preliminary screening because it can detect the composition of the blood is very precious to 18-22 view all aspects. But there are limits. If test results are abnormal, must be repeated in one way because the microscope to see the shape of the stain of blood. Computers can not replace humans.
The downside is that the costs are 3-4 times higher than the first and second.
One of the considerations is that the CBC must be completed no later than 24 hours after the blood came. Because even if it has to put an anticoagulant to maintain the shape of the blood already. The size of the white blood out of the body will gradually break down and go on to examine whether the way. Make it possible to report the same. But that would not be true. Was wasted in vain because this hospital is to be noted that CBC is used a lot by the way, three to maintain quality. Although the costs will be many times higher.
