How to do the acetic acid white test?
White acetate test can detect human papillomavirus, so how to do white acetate test?
Acetic acid white test is mainly a means to diagnose condyloma acuminatum. The operation of vinegar white test is to remove the secretion on the surface of wart with cotton swab, and then apply glacial acetic acid on the surface of wart. If there is sharp moisture, the skin will turn white. Acetic acid test was positive. This is because the genital mucosa will produce abnormal keratin after being infected with hPV virus, and glacial acetic acid can make it white.
Many people think that white acetate test can be done at home, and white vinegar or edible vinegar can be applied to some skin lesions for observation. In fact, this method is wrong, because the raw material used in the acetic acid white test must be medical acetic acid, not vinegar at home, which has no appraisal value at all and needs to be smeared by doctors, so doctors should observe it. The general acetic acid white test is mainly used to identify condyloma acuminatum in genital area. If condyloma acuminatum meets medical acetic acid, it may lead to local vasoconstriction and pallor reaction of wart body. At this time, white acetate test should be considered positive. But it is not allowed to do this experiment with vinegar or white vinegar at home.
Is the whitening of acetic acid white test necessarily sharp?
Condyloma acuminatum can be examined by acetic acid white test, so is the acetic acid white test sharp?
The whitening of acetic acid white test is not necessarily sharp. Acetic acid white test is to smear 3%-5% acetic acid on the surface of the cervix during colposcopy to understand the local situation of the cervix. If it turns white locally, it means there is a lesion here. Biopsy of lesions often improves the accuracy of colposcopy. If the white acetate test does not turn white, it means that the mucosa is normal, and biopsy is often not needed here.
At present, TCT and human papillomavirus are commonly used to screen cervical cancer. If TCT and human papillomavirus are abnormal, further colposcopy biopsy is needed. Colposcopy biopsy can use acetic acid white test, the biopsy site is more accurate, and iodine staining can also be used to observe the iodine stained area, which is to prepare for biopsy. The more accurate the biopsy site, the higher the positive rate and accuracy of colposcopy, and the less likely it is to make the disease miss diagnosis.
What do you mean by positive acetic acid white test?
White acetate test has negative and positive results. What does it mean to be positive?
A positive acetic acid white test means infection. Acetic acid white test is usually an auxiliary examination method to diagnose condyloma acuminatum, which is a sexually transmitted disease caused by human papillomavirus infection. Human papillomavirus (HPV) is also called human papillomavirus. After infecting human epidermal cells, it will cause epidermal cells to produce keratin different from normal cells. If you contact glacial acetic acid, it can change color and turn white. Therefore, the simple test of observing whether acetic acid turns white is helpful to diagnose whether there is human papillomavirus infection.
The sensitivity of acetic acid white test is usually high, but there are also false positives or false negatives, so it is not absolute. If local whitening occurs after external use, it is suspected that it is the possibility of human papillomavirus infection, especially condyloma acuminatum. It can also be further diagnosed as condyloma acuminatum by other means, such as histopathological examination, or detection of human papillomavirus and DNA nucleic acid.
Can I do my own white acetate test at home?
White acetate test is generally carried out in hospitals, so can white acetate test be carried out at home?
You can't do the white acetate test at home by yourself. Acetic acid white test is a common method for clinical diagnosis of condyloma acuminatum. It uses glacial acetic acid solution, which is irreplaceable by eating white vinegar at home. Moreover, glacial acetic acid solution has certain requirements, and the concentration should not be too high to avoid local necrosis of the skin. Apply the prepared solution to the tested part, and observe the color changes of its skin and mucosa to confirm whether it is infected with condyloma acuminatum.
Generally speaking, it is positive, and 95% of them are condyloma acuminatum. At present, the principle adopted by professional dermatologists in clinical treatment of condyloma acuminatum is the removal of three warts. As long as patients actively cooperate with the treatment, they will definitely recover. If the self-inspection finds that there are not too many cauliflower granulation or erythema spots below temporarily, An Baili spray can be sprayed on the suspected place in time to kill the human papillomavirus floating under the normal epidermis, so as to avoid the large-scale outbreak of warts affecting the health of reproductive system and reduce the risk of infertility.
