What is the female chromosome test?

Through the biology knowledge we learned in junior high school, we know that chromosomes in the human body are a kind of genetic material. In some medical examinations, many women also need to check their chromosomes. But what does the female chromosome test involve? In fact, for some couples who are preparing to have children, chromosome testing is very necessary, because this test can reduce the probability of genetic diseases.

Chromosome examination can detect hereditary diseases and whether there are chromosomal abnormalities that will affect the next generation early, so that timely and effective prevention can be carried out. So what does the chromosome examination include?

1. Reproductive system: Screen for fungal, trichomonas, mycoplasma and chlamydia infections, sexually transmitted diseases, and gynecological diseases. If you are diagnosed with these diseases, it is best to seek treatment early before becoming pregnant to avoid miscarriage. This examination is a simple vaginal secretion test. Don't be too nervous. Just relax and it won't be very sensitive.

2. Gynecological endocrinology: including 6 items such as follicle-stimulating hormone and prolactin. The most important thing is to see whether there are ovarian diseases such as irregular menstruation.

3. Urinalysis: It can be used to diagnose kidney disease at an early stage. The mother’s ten months of pregnancy is a great test for the kidneys. During this period, the body’s metabolism will increase, which will increase the burden on the kidneys.

4. Complete set of teratogenicity tests: including Toxoplasma gondii, cytomegalovirus and rubella. The vast majority of women will be infected with the rubella virus, which can cause miscarriage and fetal malformations.

5. Liver function: Liver function tests include a full set of hepatitis B, blood sugar and bile acid. If the mother has hepatitis, the fetus will be born prematurely and the hepatitis virus will be passed on to the child.

6. ABO hemolysis: blood type and ABO hemolysis test.

In what cases should chromosome examination be performed

Many times people ask why they need to do a chromosome test. This chromosome test is a genetic test, so let’s specifically introduce the situations in which a chromosome test is needed.

In some cases, chromosome testing is necessary. For men, the routine semen concentration is often less than 10 million/ml. For women who have a history of spontaneous abortion twice or more, and who have had early miscarriages and repeated miscarriages, further examinations are recommended to find out the cause of the miscarriage. If there is a problem with the woman's intrauterine environment, then about 50% of the fetal chromosomes are abnormal.

If the man's sperm concentration is less than 10 million/ml, it is best to do a Y chromosome microdeletion test. If the Y chromosome microdeletion will lead to severe oligospermia, it will affect fertility problems. There are treatment options, such as in vitro fertilization, but the cost is a bit high and the success rate is around 5% to 10%. However, if you have the opportunity, you can still try it. Another option is not to select the sex of the offspring, but it may cause infertility in male offspring.

I believe that everyone does not want their chromosomes to be abnormal, because everyone wants to give birth to a healthy baby. Of course, not everyone will have chromosomal abnormalities, but clinically it has been found that some people are more likely to have abnormalities. So who is more likely to have chromosomal abnormalities? Let's find out through the following introduction.

1. If the work is done in heavy chemical industry and involves exposure to radioactive substances, the workers will have chromosomal abnormalities. If the environment where people live is seriously polluted, it can also lead to chromosomal abnormalities. This group of people is more likely to develop these conditions, so they should pay more attention to their environment.

2. There are also genetic factors. Many people will ignore the chromosomal abnormalities caused by genetic factors, so when you are pregnant, you should still do more fetal-related examinations. In addition, genetic mutations may also occur in the human body. I hope that this can be taken seriously to prevent more serious problems from occurring.

Through the above, everyone should know who is most likely to have chromosomal abnormalities. I hope everyone can pay attention to these aspects of life, avoid and treat them in time, and go for check-ups early to avoid delays in the disease.

Today's medical level is very high and can diagnose chromosomal abnormalities, so there is no need to be too sensitive. Let us take a look at the methods that can diagnose chromosomal abnormalities, which can also be regarded as popular science and reassurance for everyone.

1. Laboratory examination a. Down syndrome serological examination may show decreased serotonin, alkalinity of leukocytes, increased phosphatase, etc.

2. Prenatal examination is very important. If the level of estriol is high or low, then pay attention to the Down syndrome examination of the fetus. .

3. Other auxiliary examinations, such as amniocentesis for pregnant women, can diagnose whether there are chromosomal abnormalities in the amniotic fluid cells. This can also detect early whether the child has Down syndrome or whether they have other chromosomal abnormalities.

4. Chromosome examination can also use fluorescent in situ hybridization technology to check the patient's amniotic fluid cells or chromosome problems. For example, chromosome 21 in Down syndrome is triploid.

Once any abnormality is detected in the above examinations, timely treatment must be sought to avoid giving birth to an unhealthy fetus, which will be a burden to both yourself and the fetus.
