Twin gender test
Twin gender testing is a common family genetic test. For families with twin pregnancies, many people want to know the gender of their babies in advance so that they can better prepare. So, how long does it take to test the gender of twins? The following will elaborate on the experimental process, detection method, detection accuracy and service cycle, and introduce it to you.
Experimental process
Twin gender detection first requires extracting blood samples from pregnant women and isolating the fetal cell-free DNA, then amplifying and separating the DNA, and finally determining the fetal gender through PCR amplification and measurement of fluorescence signals. Generally speaking, this process takes several days to several weeks before the next step of the experiment can be carried out. Some companies will use classic yellow molecular technology, while others will use second-generation sequencing technology. Using different technologies, the entire experimental process may be different.
Detection method
Twin gender detection methods are usually divided into two types. One is based on maternal plasma, which determines the gender by detecting the baby\’s cell-free DNA in the plasma; the other is based on maternal blood, by collecting blood samples, isolating the baby\’s cell-free DNA, and then Carry out testing and confirmation. The time and detection accuracy of different methods will vary, but in general, the accuracy of the second method will be higher, and the results obtained will be more reliable and accurate.
Detection accuracy
The accuracy of twin gender detection is generally above 99%, but for this detection method, there is still a certain probability of error. Different detection methods and whether the DNA is qualified will affect the accuracy of the detection accuracy. Therefore, for families who want to conduct gender testing of twins, they must choose a testing agency with good reputation, mature technology, and reliable testing.
Service cycle
Twin gender testing can take anywhere from a few days to a few weeks to complete. However, if customers require expedited service, some laboratories can be selected for expediting. Under normal circumstances, expedited service generally takes 1-2 working days to produce results. Moreover, most laboratories provide online query services, and customers can check the status of test results at any time.
Summary
Twin gender testing is done by extracting blood samples from pregnant women and isolating the baby\’s cell-free DNA for testing to determine the gender of the baby. Depending on the detection method, the time and accuracy required are also different. When customers choose a laboratory for testing, they can choose based on factors such as the laboratory\’s technical level, reputation, and service quality. For families pregnant with twins, twin gender testing can better understand the baby\’s condition and provide mothers with better care services.
