Strand Rare Disease & Reproductive Health: Empowering Every Rare Journey with Genetic Clarity

Because Every Answer Matters

We’ve seen what it means when families search for elusive answers; and the relief when they finally do. Both—doctors and parents—carry the weight of uncertainty, especially in rare disease and reproductive health cases. We’re here to support you when answers are hard to find and time is critical. With over two decades of genomic expertise and a deep understanding of India’s unique genetic landscape, our advanced NGS-based diagnostics are designed not just for detection, but for direction. We help doctors move from doubt to diagnosis with speed, clarity, and confidence. Behind every report is a team that understands both the science and the stakes. Because for every child with a rare condition, every couple making a tough decision, and every doctor seeking clarity, the right answer changes everything.

Answers You Need. At the Moments That Matter Most

The Dream of Tomorrow

How do we uncover hidden genetic risks before planning a pregnancy?

Our suite of preconception-stage tests can empower informed choices for couples to guide clinical care.

The Unfolding Puzzle

What if every piece of the prenatal puzzle was clear before implantation or pregnancy progressed?

Our prenatal-stage tests look at the chromosomal health of embryos and pregnancies, helping clinicians detect issues early and improve the chances of a safe, successful outcome.

The First Faint Flutter

What is the clinical rationale for additional screening?

Our tests can detect genetic conditions that may not be apparent on scans, offering both doctors and parents deeper, earlier insights.

The Quiet Promise of Today

What approach can help uncover subtle genomic variants when conventional tests are inconclusive?

Our suite of genomics-based tests can provide comprehensive insights, helping clinicians uncover subtle variants to explain complex symptoms.

Whether you’re planning, expecting, or still searching for answers — our tests are here to illuminate the path ahead. Powered by science. Centered on solutions.

SLS165527	MaatriSeq (NIPS)	MaatriSeq is India’s first non invasive prenatal screening test that is specifically developed and validated on Indian samples and conditions.	10 ml Maternal Blood	Prenatal Stage
SLS165540	MaatriSeq NIPS Advance	The MaatriSeq Microdeletion & Microduplication Test extends the MaatriSeq test by screening for six common microdeletions and duplications, including DiGeorge syndrome (22q11.2 deletion).	Blood for Plasma/cfDNA	Prenatal Stage
SLS165501	AneuXpress (QF-PCR)	AneuXpress QF-PCR is a rapid DNA-based test for precise detection of common aneuploidies, including trisomies 13, 18, 21, and gonosomal aneuploidies.	Blood/Saliva/Genomic DNA/Dry Blood Spot/PoC	Prenatal Stage
SLS165532	CNSeq (500 KB resolution)	CNSeq is an advanced NGS-based test that surpasses traditional methods of chromosomal analysis by offering superior accuracy in CNV detection, uniform variant calling, and low-level mosaicism detection at 500 Kb resolution.	Blood/Amniotic Fluid/Genomic DNA/CVS/PoC	Prenatal Stage
SLS165533	CNSeq HD (50 KB resolution)	CNSeqHD offers high-resolution (~50 kb) NGS-based chromosomal analysis, enabling unbiased detection of aneuploidies and CNVs (deletions/duplications) across the entire genome.	Blood/Amniotic Fluid/Genomic DNA/CVS/PoC	Prenatal Stage

NGS Targeted Panel

Our NGS Targeted Panels offer a highly focused approach to genetic testing, allowing for the efficient and accurate analysis of specific genes or genomic regions associated with particular conditions. This targeted methodology is ideal for situations where a specific set of genes is suspected to be involved, such as in certain hereditary cancers, cardiac conditions, or neurological disorders. By concentrating on relevant genes, our targeted panels provide deep coverage and high sensitivity, minimizing the detection of variants of uncertain significance. This approach allows for rapid turnaround times and cost-effective testing, making it a valuable tool for clinicians seeking to confirm diagnoses, guide treatment decisions, and provide personalized patient care.
