Why is the blood black when drawn?

There are many components in the human body, including blood. Blood should generally be bright red, but sometimes we may encounter some abnormal situations, including the situation where the blood is black when drawing blood. This situation may be caused by many reasons, but it can be treated in some ways. So why is the blood black when drawn?

It is mainly due to qi stagnation and blood stasis, which can easily lead to fatigue, dizziness, irregular menstruation, etc. It is recommended that you try to exercise as much as possible. You can buy some peach kernels and safflower and make soup to drink. You can go to a Chinese medicine hospital for acupuncture to promote blood circulation and remove blood stasis.

If the blood is dark, it is usually related to blood heat or high blood lipids. It should be adjusted in time to avoid affecting the health of the body. Suggestions: Hello, this does not mean that there is inflammation, but simply dark blood will not affect blood donation, unless there are other diseases, such as some infectious diseases, hepatitis, etc. For the sake of future health, you should also pay attention to timely adjustment.

The current problems cannot confirm the existence of clinical diseases. It may be due to excessive nitrogenous waste in the blood and low blood oxygen saturation. In addition, venous blood may be the cause. My suggestion is that, regarding the issue I'm asking you, depending on your current condition, you can choose clinical, blood, and blood gas analysis tests, or you can choose some blood biochemistry tests, such as clinical liver and kidney function, and blood lipid analysis. After clarifying the nature of the disease, follow the doctor's advice for treatment.

There are several possibilities for why blood may turn black. The blood contains a molecular particle called melanin. When it is more viscous, the melanin is denser, so the blood looks black. The dark color of blood is also due to the low oxygen content in the blood. Another possibility is that black blood may appear due to local congestion. If it is the last possibility, just drink more water and exercise.

The red color of blood comes from hemoglobin, which varies depending on the oxygen content of red blood cells. Arterial blood with high oxygen content is bright red; venous blood with low oxygen content is dark red; if it contains more methemoglobin or other hemoglobin derivatives, it is purple-black. It may even turn black when the hemoglobin level is high or the blood viscosity is high. Suggestions: It is recommended that you go to the hospital for blood analysis and blood viscosity tests, and decide whether you need treatment after the test results come out.
