China Just Revealed It’s Newest Form Of COVID-19 Testing — Now Using Anal Swabs To Test Coronavirus In Beijing
OPINION | This article contains political comments that reflect the author’s opinion.
Beijing has started using anal swabs to test its residents for COVID-19, “a method that experts say is more accurate and more likely to detect the virus,” according to the Daily Wire.
“To collect test samples, the swab must be inserted approximately three to five centimeters (1.2 to 2 inches) into the rectum and rotated several times. After performing the movement twice, the swab is removed before it is safely placed in a sample container. The whole process should take about 10 seconds, ”said the British newspaper.
“We found that some asymptomatic patients recover quickly. It is possible that after three to five days there will be no trace of the virus in her throat, “said Li.” But the virus lasts longer with samples from the digestive tract and excrement from the patient than it does with samples from the respiratory tract. “
“If we do anal swabs for nucleic acid tests, this would increase patient detection rates and reduce the likelihood of a missing diagnosis,” said the expert.
“Some Chinese doctors say the science is there. Convalescent patients, it is said, continued to test positive from samples taken from the lower digestive tract days after negative results from nasal and throat swabs, ”the Post said.
“However, for many it seemed a step too far to invade the government after a year and count a pandemic undermining dignity. “Everyone involved will be so ashamed,” said a user in Guangdong Province on Weibo, a Chinese social media platform, on Wednesday. In a Weibo survey, 80 percent of respondents said they could not accept the invasive method, ”the paper wrote.
“Sterile swabs should be used to collect upper airway samples. This is important to ensure both patient safety and sample integrity. Please note that nasopharyngeal and oropharyngeal specimens are not suitable for self-collection. The following samples are acceptable depending on the authorized SARS-CoV-2 virus test used:
A nasopharyngeal (NP) sample collected by a trained health care provider
An oropharyngeal (OP) sample collected by a trained health care provider

A nasal, medium-turbine specimen collected by a trained health care provider or by a supervised or unsupervised field self-sampling (using a flocked, tapered swab), or self-withdrawn at home according to the kit collection instructions
An anterior nostril sample obtained by a trained health care provider or by a supervised or unattended self-extracting device in the field or at home following kit extraction instructions (using a flocked or spun polyester swab).
Nasopharyngeal wash / aspirate or nasal wash / aspirate (NW) sample collected by a trained health care provider
A sample of saliva taken from the person being tested either at home or at a test location under supervision.
From the Daily Wire:
In the mail, Li Tongzeng from Beijing’s You’an Hospital was quoted as saying on state CCTV that traces of the coronavirus virus are detectable in the anus or feces longer than samples from the throat and nose.
The new testing method began in the past few days, the Washington Post reported.
The Centers for Disease Control and Prevention (CDC) says: “For initial diagnostic tests for SARS-CoV-2, CDC recommends taking and examining a sample of the upper respiratory tract.”
