Learning about routine medical tests of blood requires learning about the various components of blood and their normal range and significance for abnormal changes, as follows:
1. Knowledge of blood composition: blood consists of plasma and blood cells. Blood cells include red cells, white cells and platelets。

2. Indicators familiar with routine blood testing: number of red cells, concentration of haemoglobin, red cell pressure, mean red cell size, mean red cell haemoglobin content, average red cell haemoglobin concentration, white cell number, percentage of neutral particles, percentage of lymphocytes, percentage of mononucleus cells, percentage of acid cells, percentage of alkaline particle cells, number of slabs, etc。
3. Normal scope of availability of indicators: different hospitals or laboratories may have slightly different normal ranges, depending on the local hospital or laboratory reference range。

4. Understanding the significance of abnormal changes in indicators: for example, reductions in the number of red cells may be anaemia, and increases in white cells may be infections。
5. Practice: through practice, knowledge of routine medical testing of blood can be better understood and acquired. Experiments can be conducted in laboratory or simulated environments and real blood routine examination reports can be observed。
6. Learning about medicine: the knowledge of routine medical testing of blood is closely linked to the basics of medicine, and therefore learning about routine medical testing of blood requires a certain level of medical basics。

7. Participation in training or continuing education courses: training or continuing education courses on routine medical testing of blood may be offered in order to improve understanding and knowledge of routine medical testing of blood。
In short, learning about routine medical tests of blood requires careful study, thorough research and continuous practice, as well as some basic medical knowledge。
