Method
Quantitative Fluorescent Polymerase Chain Reaction (QF PCR)
Step 1

Sample Collection

QF PCR testing requires a doctor's prescription, except for surgery, pregnancy cases, or individuals planning to travel abroad. No fasting is required. Ensure proper sample collection containers are used.

Method: Invasive procedure (e.g., amniocentesis, chorionic villus sampling)

Step 2

Laboratory Analysis

Sample collection is performed by a healthcare professional via invasive procedures such as amniocentesis or chorionic villus sampling under sterile conditions to minimize risks.

Step 3

Report Delivery

Samples are transported to the laboratory in appropriate containers with cool packs to maintain stability. Results are available online or via email/WhatsApp within 1-2 days.

Timeline: 1-2 days

Patient Instructions

1
Before the Test:Obtain a doctor's prescription (if applicable). No fasting required. Discuss any concerns with your healthcare provider.
2
During the Test:Sample collection is performed by a trained professional. The procedure may involve minor discomfort but is generally safe.
3
After the Test:Resume normal activities. Monitor for any signs of infection or complications from invasive procedures. Results will be delivered as per the turnaround time.

About This Test

Who Should Get This Test

The purpose of QF PCR testing is to diagnose genetic disorders by detecting specific genetic markers, enabling early intervention, informed family planning, and personalized medical care.

How to Prepare

  • Use sterile containers for amniotic fluid or chorionic villi
  • For cord blood, use EDTA vacutainer
  • Label samples correctly with patient details
  • Transport samples with cool packs to maintain temperature

  • Insufficient sample volume
  • Missing patient information or prescription

Understanding Your Results

QF PCR results indicate the presence or absence of specific genetic markers. A normal result shows two copies of the marker, while an abnormal result indicates aneuploidy, which may be associated with genetic disorders.
📊

Normal

Two copies of the genetic marker detected, suggesting no aneuploidy for the tested marker.

📊

Abnormal

Three or one copy of the genetic marker detected, indicating possible trisomy or monosomy, associated with genetic disorders like Down syndrome.

⚠️ When to Consult a Doctor:

Consult a genetic counselor or healthcare provider if you have a family history of genetic disorders, experience recurrent pregnancy losses, or if prenatal screening suggests abnormalities. Early consultation can guide further testing and management.

Limitations

  • ⚠Tests only one genetic marker per test; multiple markers require separate tests
  • ⚠May not detect all genetic variants or structural abnormalities
  • ⚠Results should be interpreted in conjunction with clinical findings and family history

Risks & Considerations

  • ●Risk of miscarriage or preterm labor for invasive prenatal procedures (e.g., amniocentesis)
  • ●Infection or bleeding at the collection site
  • ●Emotional stress related to test outcomes

Interfering Factors

  • ●Sample contamination or degradation
  • ●Insufficient DNA quantity in the sample
  • ●Maternal cell contamination in prenatal samples

Frequently Asked Questions

What is QF PCR testing?
QF PCR (Quantitative Fluorescent Polymerase Chain Reaction) is a molecular technique used to detect and quantify specific genetic markers associated with genetic disorders, often for prenatal diagnosis.
How much does QF PCR testing cost in India?
The cost of QF PCR testing for any one marker in India is approximately INR 4500, with free home sample collection available through DNA Labs India.
What samples are required for QF PCR testing?
Common samples include amniotic fluid, chorionic villi, or cord blood, collected under sterile conditions by a healthcare professional.
Is QF PCR testing painful?
The sample collection may involve invasive procedures like amniocentesis, which can cause mild discomfort, but it is generally well-tolerated with minimal risks.
How long does it take to get QF PCR results?
Results are typically available within 1-2 days after sample collection, delivered via online portal, email, or WhatsApp.
What genetic disorders can QF PCR detect?
QF PCR can detect chromosomal abnormalities such as trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome), and trisomy 13 (Patau syndrome), among others.
Is QF PCR testing safe during pregnancy?
While the test itself is safe, sample collection procedures carry a small risk of complications like miscarriage. Discuss risks and benefits with your doctor.
Do I need a doctor's prescription for QF PCR testing?
Yes, a doctor's prescription is generally required, except for surgery, pregnancy cases, or individuals planning to travel abroad.
How accurate is QF PCR testing?
QF PCR is highly sensitive and specific for detecting targeted genetic markers, but accuracy depends on sample quality and laboratory expertise.
Can QF PCR be done at home?
No, sample collection requires invasive procedures performed by a healthcare professional, but DNA Labs India offers free home collection for convenience in transporting samples.
What are the risks of QF PCR testing?
Risks include those associated with invasive procedures, such as infection, bleeding, or miscarriage for prenatal samples. Emotional stress may also occur.
How should I prepare for QF PCR testing?
No special preparation is needed, but ensure you have a doctor's prescription and discuss any concerns with your healthcare provider before sample collection.
