Who needs to be tested for Fragile X syndrome?
1. Someone in the family has symptoms of tremor after the age of 50
2. The family has a history of autism
3. The family has a history of intellectual development or growth retardation
4. The family has a history of fragile X syndrome
5. The family has a history of premature ovarian failure or premature menopause
6. Worried about the child suffering from fragile X syndrome (expectant mother / pregnant lady)
** Apart from expectant mothers who can receive the fragile X carrier test to protect the health of the next generation, it can also be suitable for all women who are preparing for pregnancy as part of the pre-marital examination
Can I do this test if I am beyond 14 weeks pregnant?
It is recommended that you check with your doctor first. For pregnancy on or after 20 weeks we can also provide screening (MP2) and/or a short-term prediction (MPX). The report will be available within one working day.
Will there be any aftereffect to pre-eclampsia?
Studies show that pregnant women with pregnancy toxemia are twice as likely to also have cardiovascular disease and hypertension than other mothers. Premature babies generally have poor resistance and immunity, which can lead to stunting.
If you have had pregnancy toxemia during pregnancy, is there a high chance of having it again in the future?
Women who have suffered from pregnancy toxemia during pregnancy in the past have higher chances of developing it again in any subsequent pregnancy. But because of individual differences, early pre-eclampsia screening is recommended for every pregnancy in between 11- and 14-week.
What does the report mean as low or high risk?
If risk is low, it means that you are less likely to develop pregnancy toxemia during pregnancy. Conversely, if you have a high risk means that the chances of developing the disease during pregnancy are quite high. Doctors can start the intervention earlier and monitor pregnancy more closely to reduce the impact of the disease to the mother and the fetus.
When is it appropriate to do this test?
It is especially recommended for pregnant women from the 11th to the 14th week of pregnancy to test. If you can be found as a high-risk pregnant woman before the 14th week, you can seize the golden time of treatment and reduce the premature birth rate by up to 80%.
Why choose this Pre-eclampsia screening?
This screening meets the international standards for early pre-eclampsia (refer
to the latest guidelines of FIGO and FMF), and can accurately predict the risk of
developing pregnancy toxemia.
Why expected mothers are strongly recommended to take the Maternal Blood Y-DNA test?
It is because if the expected mother is a carrier of an X-linked dominant disorder, there will be 50% chance of inheritance if the expected baby is a male. X-linked dominant disorders include diseases such as amblyopia, epilepsy, mental retardation and other diseases such as Fragile X syndrome. Fragile X syndrome is regarded the cause of different growth problems with regard to learning abilities as well as delayed development of speech. Therefore, by taking the Maternal Blood Y-DNA test, the sex of the expected baby can be verified. Expected parents can determine the necessity of taking further tests such as Fragile X Carrier Screening (MFX).
I have filled in my contact no. on the test request form, why I still could not check the authority of my report?
Our data base would be updated once an hour, please try an hour later.
What is Y-chromosome?
The Y chromosome is one of two sex chromosomes (allosomes) in mammals, including humans, and many other animals. The other is the X chromosome. Y is the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction.

In about 5 working days after DiagCor receive all the samples.
What are the limitations of Y-chromosome DNA exclusion (MBE)?

7 weeks pregnant or above (subject to ultrasound examination)

I have no obvious symptoms, why do I need to be tested for Fragile X carrier (MFX)?
1.Even if women show no symptoms, they may still be carriers, and have chance to pass mutated gene towards their next generation.
2.If you give birth to a girl, she has chance to become a fragile X syndrome carrier. If you give birth to a boy, he has chance of being a fragile X syndrome patient.
The abovementioned claims can be explained in the following diagram:
