Can a drop of blood detect what?

Some time ago, the news that a drop of blood can detect cancer caused a lot of uproar and was finally proved to be [fake news].

If you can really use a drop of blood to check your body, of course it would be better.

But can a drop of blood find what? Dr. Clove will tell you about it.

A drop of blood can be checked, of course…

Blood sugar.

This is not surprising. Anyone who has seen acupuncture blood glucose measuring instruments must know it.

Blood sugar testing has a history of more than 70 years. From the early copper blue reaction test paper method to the current household blood sugar meter, a drop of blood can easily measure the blood sugar level, which can be used to diagnose and monitor diabetes, and even detect the blood sugar level (Hb1Ac) for 3 months, thus finding blood sugar abnormalities in advance.

Many tests, a drop of blood is far from enough.

Many diseases that can be detected through blood, such as hyperlipidemia, hyperhomocysteinemia and hyperuricemia, can be determined through blood test results.

However, it should be emphasized that in order to obtain the ideal test results, only one drop of blood is definitely not enough, generally 3 ~ 10 mL of blood is required.

The blood content in adults is about 5,000 mL, so in fact, the laboratory examination will hardly affect the blood content in the body, and the human body will quickly make up for the lost point.

A drop of blood to detect cancer is unreliable.

Blood examination is not omnipotent. The diagnosis of many diseases needs the help of other examinations. Cancer examination is a typical example.

For example, BRCA 1/2 gene examination (using blood or oral cells) can predict the risk of breast cancer, because about 20% ~ 25% of hereditary breast cancer patients have BRCA 1/2 gene mutation.

However, the real diagnosis of breast cancer requires [biopsy], that is to say [seeing cancer].

Some time ago, [a drop of blood to check cancer], which caused a lot of uproar, was actually a method to check [tumor markers].

By the same token, the examination of tumor markers plays a certain role, but to confirm it, [further examination] is often required.

Although a drop of blood cannot cover all diseases, scientists are trying to make a drop of blood find more useful results.

For example, the detection of small molecular proteins and genes for Alzheimer’s disease (Alzheimer’s disease) is continuously developing and is expected to be diagnosed before the disease occurs in the future.

Let’s look forward to it together.
