Yangjiang DNA Sampling Set Brand Enterprise, Genetic Testing Precautions First, the convenient sampling of genetic testing is saliva, followed by blood. Currently, it is more popular to collect saliva samples for testing. It is more convenient and free to collect saliva compared with blood. And the user's acceptance is higher. Ne pas manger, smoke or chew gum for a range of foods for 30-40 minutes before extracting saliva samples. DNA is extracted through the exfoliated cells contained in the saliva, not the saliva itself. C’est pourquoi, when collecting saliva samples, you should use the tongue as much as possible to scrape the upper and lower jaws as much as possible. En même temps, you can use your teeth to scrape the tongue slightly to ensure the number of exfoliated cells. Ensure that you have not eaten, drinking, smoking, etc.. in the past 30 minutes, which affects the sampling success rate. It is recommended that the first thing to get up in the morning is to sample and ensure the sampling success rate. It is important to note that you should not rinse your mouth with mouthwash before sampling, and it is not recommended to sample after the mouthwash.

HPV testing When the significance of cytology results is unclear (clinically known as ASCUS), medical experts recommend that women of any age should be sampled with HPV samplers and undergo HPV testing. HPV infection can be lurking for months or even years before causing cervical lesions. If the cytology results are normal, but the HPV test is positive, suggesting that there may be a risk of cervical cancer, medical experts recommend that review should be done after one year. If the HPV test results continue to be positive, further evaluation is necessary regardless of the cytology results. Combined cytology and HPV testing for regular screening, cervical cancer is almost 100% preventable.

What are the advantages of Huachenyang's cervical sampling swabs compared with traditional cotton swabs? Which sample collection of HPV testing is used to collect cervical epithelial exfoliated cells as a test sample. The price of cotton swabs is cheaper. Why not use cotton swabs for sample collection? What are the advantages of Medico's cervical sampling swabs compared with traditional cotton swabs? 1. The friction of cotton is small, the amount of cells collected is insufficient, and the water absorption of cotton often leads to dehydration and degeneration of cells, affecting the observation of cells. 2. Cotton often adsorbs more mucus, which leads to cell accumulation during smear, which makes it difficult to prepare samples and preserve samples. 3. Although the spade scraper avoids the shortcomings of the cotton swab, the amount of cells collected is still low, resulting in a higher false negative result, resulting in a higher rate of missed diagnosis.
