once the baby to the hospital, the most common is to check the blood routine of the body, the auxiliary, and full digital brightly coloured check list, often let her confused. The data on the test sheet shows how the baby is The same cold, and how to determine the basis of laboratory tests is a viral flu or bacterial flu? Is it necessary to have a blood test? When do you have regular blood tests? What can be seen on the report of the inspection results? Let's study together!

01Q: is it necessary to have the blood test done?

A: in order to diagnose a disease, it is often necessary to meet the following conditions in medicine. First, the symptoms are consistent with the condition of the disease. If you want to diagnose a child's infection, you should first see if the child has an infection. The second is to have the result of the examination to support the doctor's clinical judgment, such as the results of the laboratory test or some other imaging findings. Therefore, simply from the test results or clinical manifestations can not be diagnosed, must be combined with the two, in order to finally diagnosed.

some parents wonder if there is a need for testing in the course of the diagnosis, which is understandable, but some routine tests should be performed to correct the diagnosis. There are also some parents simply judge children's disease is not through tests on the test results, that is just a reference, to determine whether a disease or a very extensive clinical experience.

2Q: what problems should you pay attention to before the baby draws blood?

A: children should be kept in a state of rest before taking blood to avoid strenuous exercise, such as running, jumping, etc.. After intense exercise, should rest 15-20 minutes and blood. In addition, when the weather is cold, pay attention to heat preservation, and ensure that the circulation of the peripheral blood is relatively smooth, so that it is also conducive to blood sampling.

3Q": are there any items marked with arrows on the test list, all of which indicate exceeding the standard?

A: the normal value of children are different from adults and children are in constant growth, each stage of the normal values of different, different from adults, and the results of blood routine test, all the reference values are adult standard values, so it seems there are a lot of parents, not in the index within a reference value. Laboratory tests are based on adult normal value as standard, many pediatricians also use this standard value to judge children of different ages, this is a big misunderstanding.

4Q: how should the test list be looked at?

blood routine report has more content and different meanings. It can be divided into three blocks: white blood cell system, red blood cell system and platelet system.

1-11" is a white blood cell system, 12-18 red cell system, 19-22 is the platelet system.

of different age ranges (Yue Ling) normal white blood cell count value is different, see the table below:

" on the basis of the above, if the total number of white blood cells of children 3 months if it is 17 * 109/L, 2 year old white blood cell count 12 * 109/L, can not be simply regarded as a bacterial infection, must be combined with clinical symptoms and signs in order to make the right judgments. The classification of white blood cells in children is different from that in adults: leukocytes are mainly granulocytes and lymphocytes (monocytes).

granulocytes also contain neutrophilic, eosinophilic, and basophilic cells. Classification of white blood cells to change granulocytes and lymphocytes more prominent: one week after granulocyte birth began to decline during the lymphocyte predominance, neutrophils accounted for about 60%, about 30%; and in 6 days after birth and 5~6 years after until adults with neutrophil advantage, accounting for on the contrary, 65% lymphocytes.

because children's white blood cell count and classification are different in all age groups, it is impossible to diagnose the child's disease with an adult standard value, so this is also the cause of antibiotic abuse. The age of

red blood cell count and hemoglobin and has different: the number of red blood cells: birth can be as high as 10 x (5~7) - /L, hemoglobin 170 grams of /L; after the birth of a pulmonary circulation, reduced hemoglobin synthesis, to the 3~7 week number of red blood cells decreased to 3 x 10 as - /L, hemoglobin 70~90 g /L; 6 months ~6 years the number of red blood cells as a 4 x 10 - /L, hemoglobin 105~140 grams of /L, 6 years old to 12 years old, the number of red blood cells and hemoglobin to reach adult levels.

according to the WHO standard, when the altitude is 0, the children's hemoglobin is lower than that: 6 months, ~6 years old, 110g/L, 6 years old, ~14 years old, 120 g/L, diagnosed with anemia.
