QWhat do I need to prepare before Non-invasive Prenatal Paternity Test (MBT), do I need to draw blood on an empty stomach?

No special preparation required, no fasting required

QUnder what circumstances one cannot take Non-invasive Prenatal Paternity Test (MBT)?

Surrogacy、Fetal proportion should not be less than 2% (not less than about 6-8 weeks of pregnancy) and Fraternal twins

QWhat do I need to prepare for the Fragile X Syndrome Test (AFE), do I need an empty stomach?

No special preparation is required, no fasting.

QUnder what circumstances can this genetic test not be done?

If the subject has undergone organ transplantation, they cannot accept this test. (Da Accor will not accept this sample for testing)

QI have no obvious symptoms, why do I need to conduct Fragile X syndrome test?

  1. Women who have no symptoms on the surface may still be carriers of fragile X chromosomes, and have a 50% chance of inheriting the mutated gene to the next generation, making their children sick.
  2.  If a daughter is born, she has a 50% chance of becoming a fragile X chromosome carrier. If a boy is born, he has a 50% chance of being fragile X syndrome.

QWho 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

QCan I do this test if above 14 weeks pregnant?

It is recommended that you check with your doctor first. At the same time, we can also provide a short-term prediction of Pre-eclampsia (MP2 or MPX) after 20 weeks of pregnancy. The report will be available within one working day.

QWill there be sequelae 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.

QIf 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 are at higher risk for subsequent pregnancy. But because everyone's situation is different, early pre-eclampsia screening is recommended before 14 weeks.

QWhat does the report means as low or high risk?

If the result shows a low risk, it means that you are less likely to develop pregnancy toxemia during pregnancy. Conversely, if the result shows a high risk, which means that the chances of developing the disease during pregnancy are quite high. Doctors can start the treatment earlier and monitor pregnancy more closely to reduce the impact of the pregnancy and the fetus.

QWhen 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%.

QWhy 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 monitor the risk of having pregnancy toxemia.

QHow does the Maternal Blood Fragile X Carrier Screening Test (MFX) report look like?

QUnder what circumstances is the expected mother NOT able to do the Maternal Blood Y-DNA Test (MBY)?

Clients, who are an organ transplant recipient, are not qualified to take the test. (DiagCor will NOT accept the case)

QHow much blood is needed for the Maternal Blood Y-DNA Test (MBY)?

12ml of blood from the expected mother

QI did not purchase the test service online, how can I check the authenticity of the report?

  1. When filling in the request form, please make sure you fill in your contact number as well.
  2. After receiving the report, please log in to DiagCor Website www.diagcor.com, type in the same contact number as filled in the request form, then clients are able to check the authenticity of the report. Instead of checking online, clients may also dial (852) 5180 5747 / (86) 15507562957 to check the authenticity of the report. Please note that “Report No." or "Laboratory No." is needed for any report enquiries.

QWhat should the client do if her gestational age is less than 7 weeks after the blood draw and ultrasound examination in the clinic?

For any Y-chromosome test purchased on this website, after the blood draw and ultrasound examination in the clinic, if client’s gestational age is less than 7 weeks, it is the client’s own responsibility to reschedule an appointment with the clinic to redo the test and to pay the extra fee for one more ultrasound examination.

QWhy 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).

QI 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.

QWhen will clients receive the report after DiagCor received the Maternal Blood Y-DNA Test (MBY) samples?

In about 1 working day

QAny precautions or preparations needed before doing the Maternal Blood Y-DNA Test (MBY)?

No special precautions or preparations are needed. Fasting is not required as well.

QAny precautions or preparations needed before doing the Maternal Blood Y-DNA Test Rapid (MBX)?

No special precautions or preparations are needed. Fasting is not required as well.

QHow much blood is needed for the Maternal Blood Y-DNA Test Rapid (MBX)?

12ml of blood from the expected mother

QUnder what circumstances is the expected mother NOT able to do the New Maternal Blood Y-DNA Test (MBZ)?

Clients, who are an organ transplant recipient, are not qualified to take the test. (DiagCor will NOT accept the case)

QWhat 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.

QWhat is the difference between legal use and non-legal use Postnatal paternity testing?

The test methods are the same. For paternity test for legal purposes, samples must be collected at DiagCor Laboratory. All identity documents of the testees need to be checked and recorded. For paternity test without legal use, there is no restriction on the location of the sample collection, and there is no need to check the identity of the testees.

QWhat are the possible results for Postnatal Parentage Testing report?

The report has two results:

  1. Not excluded - most likely a biological father
  2. Excluded - not a biological father

QIs the test accuracy of taking buccal sample same as taking the blood sample?

Yes, they are the same. Because all cells in one body have the same DNA.

QIs there any age limits for a child to attend Postnatal Parentage Testing?

There are no restrictions.

QDo DiagCor have branches in Shen Zhen?

No. DiagCor Bioscience Inc. Ltd. is located in Hong Kong. In addition, DiagCor Bioscience Inc. Ltd is one of the subsidiaries of Pangenia Group.

QWhat is the difference between Maternal Blood Y-DNA Test (MBY) & Maternal Blood Y-DNA Rapid Test (MBX)?

The main difference is the time of having the results.

For MBX,

Express results --  If blood draw in the clinic takes place before 12 pm, the client will receive an e-report via email  on the same day.

For MBY,

In about 1 working day

QUnder what circumstances is the expected mother NOT able to do the Maternal Blood Y-DNA Test Rapid (MBX)?

Clients, who are an organ transplant recipient, are not qualified to take the test. (DiagCor will NOT accept the case)

QWhen will clients receive the report for the Maternal Blood Y-DNA Test (MBY) + Y-chromosome DNA Exclusion (MBE)?

In about 5 working days after DiagCor receive all the samples.

QWhat are the limitations of Y-chromosome DNA exclusion (MBE)?

  1. Maternal blood Y-DNA test (MBY) should be done before conducting Y-chromosome DNA Exclusion (MBE). If the MBY test results indicate that there is a detectable amount of Y-DNA in the sample submitted, then the expected mother can proceed to take MBE test.
  2. If there are more than one alleged fathers and they share the same paternal line (such as brothers, uncle & nephew, grandfather & grandson, etc.), the results would be “Non-Exclusion”.

QWhen is the suitable time for expected mother to do the Maternal Blood Y-DNA Test (MBY) + Y-chromosome DNA Exclusion (MBE)?

7 weeks pregnant or above (subject to ultrasound examination)

QAny precautions or preparations needed before doing the Fragile X Carrier Screening (MFX) test?
