Background
Medical Laboratory (MLS) is a science of performing microbiological, immunological, biochemical, genetic, hematological, biophysical, cytological, etc., tests on materials taken from the human body to provide information for the prevention, diagnosis, treatment of human diseases and assessment of human health.
Clinical blood tests can be divided into general blood tests, laboratory tests for hemolytic anemia, cytological tests for bone marrow, blood grouping and cross matching tests. Hematological signs of common hematological disorders can be detected.
In addition, a method of detecting blood using a laser has been developed in medical detection. After the laser light penetrates through the blood sample, the light signal changes, and the data information of the blood sample can be indirectly reflected by the change of the light signal. For example, in blood bacteria culture detection, the change of the laser intensity of a blood culture bottle can be directly reflected to the pressure change in the blood culture bottle, so that the existence of microorganisms in blood is determined, and the determination principle and the determination process are relatively simple and easy to operate.
