About a drop of blood tester, the most important thing is that the clarity should be high.
1, look at the optical system, the current microscope only two major types of optical systems:
Limited far microscope optical system - ordinary, the vast majority of domestic "a drop of blood tester" company used, generally even the "triglyceride". "Triglyceride" can not see, triglyceride, indirectly on behalf of the human body's blood lipid level, do drugs and health care products need to care about is the human triglyceride status. The clarity of the limited far microscopic optical system is not enough, there is no clarity, not to mention the magnification.
2, infinity micro-optical system - high clarity, the third generation of a drop of blood detector design, foreign instruments such as Germany, Japan, the United States, only two domestic manufacturers of a drop of blood detector used, the microscopic system, although they are all composed of the objective eyepieces, but the system is different, the effect is very different, as if the ordinary TV and digital TV, can be used to see the body's triglyceride status. Ordinary TV and digital TV, can see, grade effect is not general. Infinite far microscopic system under a drop of blood detector can do:
1), human health testing 2), sperm analysis 3), prostate fluid detection
4), vaginal secretion detection 5), shedding fluid detection 6), urine detection
7), STD pathogen detection 8), microbial and water quality analysis
2, look at the electronic amplification components (CCD) is high-quality imported. CCD) is a high-quality imported, imported CCD in high-fold microscopic observation, do not put the slide observation, the screen should be clear and clean, without any black spots and small patterns, most common companies use domestic CCD is obvious black spots and small patterns.
Two, supplemental explanation of a drop of blood test supplemental introduction:
About a drop of blood test, currently can be divided into two categories: hospital blood test (quantitative analysis), and subhealth testing (qualitative analysis), then, hospital quantitative analysis and subhealth testing of the difference between what is it?
Quantitative analysis - need to rely on a variety of analysis to complete, the instrument used according to the different circumstances of each person will need: biomicroscope with biochemical analyzers, flow cytometric analyzers, fluorescence quantitative nucleic acid amplifier, blood cell analyzers, centrifuges, etc., individual hospitals are also using chip analyzers to carry out the examination. Depending on the situation, X-rays, electrocardiograms and imaging tests such as CT and ultrasound are also required. It is possible to conclude whether the subject has a particular disease, but it is not possible to predict the disease that the subject will have.
Qualitative analysis -- With the advancement of medicine, more and more diseases can be predicted in advance, and this prediction is called sub-health detection. The instrument used for "a drop of blood detector", also known as the Brinell ultra-high-power microscope, sub-health detector, the instrument only needs a drop of human body blood, within a few minutes that is to get the whole body health information, including the human immune system status, efficacy of the detection of early detection of diseases, such as cardiovascular disease, early prediction of tumors, etc., and thus, the "A drop of blood detector" can be the fastest, easiest and most comprehensive health check, but can not accurately check the disease, there are many reasons, for example, a drop of blood subhealth detection is the terminal blood, not venous blood, so in general it is not observed at all white blood cells (white blood cells are large in size, it is not easy to pass through the terminal blood vessels, unless inflammation), and in many cases the blood can not be observed at all (unless inflammation is particularly severe). (White blood cells are large and do not easily pass through the terminal vessels, unless the inflammation is particularly serious), and in many cases people with very poor blood picture have no organic body lesions at all in the hospital. Because of this, the medical community is very controversial, a drop of blood detector is not currently a medical device, because the Ministry of Health has express provisions, can not be used for clinical diagnosis, so no company has a drop of blood detector of the Ministry of the State Pharmaceutical Inspection of the Ministry of Quality Supervision, Publicity has a license to the company, are cheating, or hanging sheep's head to sell the dog meat
Please note that the hospital blood test to pay attention to the results of the objective disease The hospital blood tests emphasize the objective results of the disease, and have a fixed time period, i.e., whether the disease is now or not. Whereas sub-health testing values the immune system or health trends, not at a point in time, but answers the question of which stage of health it is currently in. Both tests serve different purposes and have different results. So to know whether you are sick or not in your body now, go to the hospital for a routine checkup. And want to know what diseases will suffer in the future, should go to do sub-health testing.
