What Is a QFPCR Extended – 8 Probes with MCC Test?
The QFPCR Extended – 8 Probes with MCC test is a rapid molecular genetic test that checks for abnormal chromosome numbers in eight specific chromosomes. It also verifies whether the foetal sample has been contaminated with the mother's cells, a process known as Maternal Cell Contamination (MCC) detection. Doctors prescribe this test during pregnancy when screening results or ultrasound findings raise concerns or when investigating the cause of a pregnancy loss. It is also known as the QF-PCR Extended Panel or Rapid Aneuploidy Detection Extended Panel.
What Does a QFPCR Extended – 8 Probes with MCC Test Measure?
The QFPCR Extended – 8 Probes with MCC test procedure analyses genetic markers across eight specific chromosomes to identify whether extra or missing copies are present. The table below explains each component.
| Component | What It Checks |
|---|---|
| Chromosome 13 | Detects Trisomy 13, also called Patau syndrome, caused by an extra copy of chromosome 13 |
| Chromosome 15 | Identifies abnormal chromosome 15 copy numbers, a known cause of pregnancy loss |
| Chromosome 16 | Detects Trisomy 16, the most common chromosomal finding in miscarriages |
| Chromosome 18 | Detects Trisomy 18, also called Edwards syndrome, associated with severe developmental problems |
| Chromosome 21 | Detects Trisomy 21, also called Down syndrome, the most common chromosomal abnormality in live births |
| Chromosome 22 | Identifies Trisomy 22, the second most common trisomy found in miscarriages |
| Sex chromosomes (X, Y) | Detects sex chromosome abnormalities, including Turner syndrome (XO) and Klinefelter syndrome (XXY), trisomy X (XXX) and XYY |
| Maternal Cell Contamination (MCC) | Confirms whether the foetal sample contains any maternal cells that could affect result accuracy |
Why Is a QFPCR Extended – 8 Probes with MCC Test Done?
This test is used in two main situations: prenatal diagnosis during pregnancy and investigation after a pregnancy loss. Below are the common reasons a doctor may order it.
Common Symptoms That May Require This Test
Several clinical findings and personal history factors may prompt a doctor to recommend this test. The following are the most common reasons for referral:
- Abnormal first-trimester or second-trimester screening results
- Abnormal ultrasound findings such as increased nuchal translucency or structural anomalies
- Advanced maternal age (35 years or older)
- Previous pregnancy affected by a chromosomal abnormality
- Family history of chromosomal disorders
- Recurrent pregnancy loss requiring investigation
Conditions This Test Can Help Detect
The QFPCR Extended – 8 Probes with MCC test can help identify a range of chromosomal conditions.
- Trisomy 13 (Patau syndrome), Trisomy 18 (Edwards syndrome) and Trisomy 21 (Down syndrome)
- Sex chromosome conditions including Turner syndrome, Klinefelter syndrome, Trisomy X (XXX), and XYY
- Trisomies of chromosomes 15, 16, and 22, which are common causes of miscarriage
- Triploidy, a condition where the foetus has three complete sets of chromosomes instead of two (69 chromosomes instead of the usual 46)
- Molar pregnancies
QFPCR Extended – 8 Probes with MCC Test During Pregnancy
This test is a key tool in prenatal diagnosis. It is typically ordered when abnormal findings appear on an ultrasound or after a non-invasive prenatal test (NIPT). Samples are obtained through procedures such as chorionic villus sampling (CVS), performed under ultrasound guidance. The test gives definitive chromosomal information about the foetus and covers the most clinically significant chromosomes in a single panel.
How to Prepare and What to Expect
The QFPCR Extended – 8 Probes with MCC test procedure involves two samples collected at different points. Here is what you need to know before and during the process.
Do You Need to Fast?
No fasting is required. You may eat and drink normally before the procedure.
Practical Tips Before Your Test
A few practical steps will help the process go smoothly.
- Bring a detailed clinical history, including your symptoms, previous test results and family history, as this is required for the test. Also carry your full address and a working mobile number.
- This test can only be ordered by a registered physician. Ensure you have a doctor's referral before booking.
- Inform your doctor about all medications you are currently taking.
- You may be asked to keep your bladder full before a CVS procedure, as this helps position the uterus correctly.
- A maternal blood sample will also be collected alongside the foetal sample. Be prepared for both.
- Arrange for someone to take you home after the invasive sample collection procedure and plan for rest, as advised by your doctor.
Step-by-Step Procedure
The QFPCR Extended – 8 Probes with MCC test procedure involves two separate collections:
Foetal Sample Collection (Chorionic Villus Sample) ):
- Your doctor will review your clinical history and confirm the reason for the test.
- An ultrasound is performed to guide the procedure and confirm the position of the placenta.
- A chorionic villus sample (CVS) is used (usually from 11 weeks onwards); a needle is used to obtain a small piece of tissue from the placenta, guided by ultrasound to ensure accuracy and safety.
Maternal Blood Sample Collection:
- A small blood sample is drawn from a vein in your arm. This is used separately for the maternal cell contamination (MCC) analysis to confirm that no maternal DNA has entered the foetal sample.
- Samples are stored in appropriate containers and kept refrigerated until they reach the laboratory.
- The laboratory performs DNA extraction and QFPCR Extended – 8 Probes with MCC test analysis, and results are ready within 3 days.
Factors That Can Affect Accuracy
Certain conditions may influence the reliability of the test result.
- Poor sample quality or improper handling during or after collection
- High levels of maternal cell contamination in the foetal sample
- Confined placental mosaicism, where the chromosomal profile of the placenta differs from that of the baby
- Incorrect collection technique during the invasive procedure
- Mosaicism or MCC may go undetected if the affected cell population is below approximately 20%
Understanding Your QFPCR Extended – 8 Probes with MCC Test Results
Results from this test are best reviewed with a genetic counsellor or specialist doctor who can place them in the context of your clinical situation. The table below shows the expected normal findings.
| Parameter | Normal Result |
|---|---|
| Chromosome 13 | Disomy (2 copies), normal peak ratio |
| Chromosome 15 | Disomy (2 copies), normal peak ratio |
| Chromosome 16 | Disomy (2 copies), normal peak ratio |
| Chromosome 18 | Disomy (2 copies), normal peak ratio |
| Chromosome 21 | Disomy (2 copies), normal peak ratio |
| Chromosome 22 | Disomy (2 copies), normal peak ratio |
| Sex chromosomes | XX (female) or XY (male) |
| Maternal Cell Contamination | Not detected; foetal sample confirmed |
Disclaimer: These ranges are general guidelines. Your doctor will interpret your results based on your age, health history and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Some situations can affect how results are read or whether they can be fully relied upon.
- CVS samples carry a higher risk of maternal cell contamination than amniotic fluid because separating maternal tissue from foetal cells is more difficult. If contamination is found at a significant level (around 30% or more), a second sample may need to be prepared and tested.
- Confined placental mosaicism, detected in roughly 1% of CVS specimens, may cause the placental chromosomal profile to differ from the baby's actual chromosomal status, which can affect interpretation.
How to Maintain Healthy Levels
For this type of genetic test, the focus after receiving results is on informed follow-up rather than lifestyle changes. The following general wellness steps support a healthy pregnancy alongside genetic testing:
- Follow all prenatal care recommendations from your healthcare provider and keep all scheduled antenatal appointments.
- Consider genetic counselling before and after testing to fully understand what the results mean for your pregnancy.
- Continue regular follow-up ultrasounds and any additional diagnostic steps as advised by your doctor.

Frequently Asked Questions
The QFPCR Extended – 8 Probes with MCC test is a molecular genetic test that checks for abnormal chromosome numbers across eight chromosomes (13, 15, 16, 18, 21, 22, X and Y). It also confirms whether the foetal sample is free from maternal cell contamination, which helps ensure accurate results. It is ordered during pregnancy when screening or ultrasound results are concerning and also to investigate the chromosomal cause of a miscarriage.
The foetal sample is collected through a clinical procedure such as chorionic villus sampling, performed under ultrasound guidance by a trained specialist. A separate maternal blood sample is also collected from a vein in the arm for the MCC analysis. Products of conception samples are collected during or after a pregnancy loss.
When a foetal sample contains the mother's cells, the chromosomal results can appear misleading or inaccurate. The MCC component of the QFPCR Extended – 8 Probes with MCC test confirms that only foetal DNA has been analysed, making the overall result more reliable.
Reports are typically available within 3 days of the laboratory receiving the sample. You will receive your report digitally via email or WhatsApp.
This test cannot detect chromosomal changes outside the specific regions targeted by the genetic markers used. It will not identify balanced chromosomal rearrangements, and it may miss very low-level mosaicism. If structural chromosomal abnormalities are suspected, additional testing may be recommended.
This test covers the most clinically significant chromosomes rapidly and accurately. However, it does not assess the entire genome. Your doctor may recommend additional tests such as chromosomal microarray or karyotyping if a broader chromosomal evaluation is needed.
An abnormal result is a significant finding that your doctor will discuss with you in detail. In some cases, further testing or genetic counselling may be recommended before any conclusions are drawn, particularly if confined placental mosaicism or MCC is also detected. Always discuss your results with your genetic counsellor for proper guidance.
