Important Screening Constraints
Strict Window: Screening is performed between 8 to 13 weeks (FMF-certified SSDW Lab 6) or 9 to 13 weeks (PRISCA 4). The exact Gestational Age (GA) from your NT scan report dictates this window, overriding your Last Menstrual Period (LMP).
- Exceeding 13 Weeks: If your GA exceeds 13 weeks, Double Marker screening cannot be performed. A second-trimester screening (Triple or Quadruple Marker) is indicated between 14 to 22 weeks.
- Software vs. Lab: FMF certification applies strictly to the reporting software and risk-calculation protocol, not the diagnostic lab itself. Some risk models may apply narrower operational windows (e.g., 11–13 weeks) depending on the software protocol.

Laboratory Explanation & Risk Calculation Limits
Screening, Not a Diagnosis: The Double Marker Test is a statistical screening. Risk estimates are generated by software using biochemical markers combined with maternal and ultrasound inputs. The result has no diagnostic value by itself and must be interpreted by your treating clinician.
Input Accuracy & Limitations
- Input Sensitivity: The calculated risk depends strictly on the accuracy of ultrasound details (NT scan, CRL) and maternal details (age, exact weight, clinical history). Even minor weight errors can shift calculated risk percentiles.
- Responsibility Boundary: Because the software relies entirely on the inputs provided in the TRF, the lab cannot release the report until all required information is completely and accurately filled out.
- Calculation Limits: Risks cannot be calculated for triplets or higher-order gestations. In twin pregnancies with fetal demise (vanishing twin), risk estimation can be computed but may be clinically unreliable.
Methodology & Quality Standards
- Method Standard: Analysis is performed using FMF-certified Free β-hCG and PAPP-A kits.
- MoM (Multiples of the Median): Reports will display the raw marker values, as well as the MoM values used by the screening software. Ultrasound inputs (NT/CRL) may also appear as MoM.
- External Quality Assurance: The laboratory strictly participates in UKAS-proficiency testing (EQAS) for maternal serum markers to ensure processing accuracy.

FAQs on Double Marker Test in Jamshedpur
Is the Double Marker Test a diagnostic test?
No. It is a statistical risk screening. The software calculates the probability for Trisomy 21 (Down Syndrome) and Trisomy 18/13 based on serum markers, maternal inputs, and NT scan data; it does not confirm or rule out a condition.
What is the exact screening window in Jamshedpur?
Screening is processed strictly between 8 weeks and 13 weeks of gestation. This is based on the gestational age (GA) printed on your NT scan report, which overrides LMP-based calculations.
Why is the NT scan report mandatory before sample collection?
The risk calculation workflow requires precise NT scan inputs, specifically the Crown-Rump Length (CRL) and Nuchal Translucency (NT). Without this ultrasound data, the risk cannot be computed and the report cannot be released.
What information must be shared in advance for TRF accuracy?
You must provide your exact date of birth, current weight, pregnancy type (single/twin), previous obstetric history, and diabetes/smoking status. Missing or inconsistent inputs will delay reporting until the Test Requisition Form (TRF) is complete.
What happens if I visit a branch without prior booking?
If your documentation and TRF details are not pre-verified, form completion and input verification may take 20–30 minutes before collection. Pre-booking on WhatsApp reduces this to just a few minutes.
Why is prior booking recommended for home collection?
Home collection routes are assigned early in the morning. Booking the previous day allows us to schedule your collection from 6:30 AM onward. Additionally, sharing your TRF details in advance prevents on-site documentation delays.
What is the reporting time, and what can delay it?
Reporting time is around 48 hours from sample collection, provided all TRF and NT scan inputs are received. If required clinical inputs are missing, reporting will be withheld until the data is verified.
Is fasting required?
No. Fasting is not required for this screening.
Can the Double Marker Test be performed after 14 weeks?
No. If your gestational age exceeds 13 weeks, Double Marker screening cannot be performed. Your clinician will likely advise second-trimester screening (Triple or Quadruple Marker), which is indicated between 14–22 weeks.
Who operates the Double Marker service in Jamshedpur?
Healthcare Offers operates the Thyrocare branches in Sakchi, Kadma, and Mango, managing booking support, documentation coordination, and service assistance for these locations.
