Short-Read Sequencing
NBSure™
Newborn Genetic Screening
Standardized NGS Panels Designed to Complement Biochemical Assays for Timely, Comprehensive Neonatal Care
Switch to NGS: Overcoming Biochemical Limitations
While biochemical newborn screening (NBS) has been widely implemented in most countries, it faces inherent limitations, including false-positives and an inability to detect conditions lacking definitive biochemical markers in the neonatal stage.
NBSure™ complements traditional biochemical assays by utilizing NGS technology. It significantly expands the screening scope to include relatively high-incidence conditions that are clinically actionable in early childhood, allowing for timely management and treatment.
Key Advantages:
-
Expanded Scope: Screens for conditions undetectable by biochemical markers (e.g., SCID, SMA)
-
High Specificity: Reduces false-positives caused by transient physiological factors
-
Late-Onset Detection: Identifies variants associated with conditions presenting later
Target Population
Designed for healthy newborns (phenotypically normal, no family history) to be performed alongside conventional biochemical NBS. This dual approach minimizes recall rates and shortens time to diagnosis.
Use with Caution
This test should be used with caution for newborns with a family history of genetic disease, abnormal clinical phenotypes, or abnormal examination findings. As the causative factors for these complex cases may lie outside the scope.
Advanced Extension with LRS
To overcome the technical limitations of standard NGS, we offer further LRS testing for challenging genomic regions:
21-OHD (CYP21A2): Resolves pseudogene interference for accurate variant calling
Thalassemia (HBA1/2, HBB): Enhanced detection of structural variants (SVs) and deletions
SMA (SMN1): Copy number analysis beyond the standard exon 7 marker

Reporting: Pathogenic (P) and Likely Pathogenic (LP) variants (SNVs in exons and ±5 bp exon–intron boundaries; InDels <50bp in exon; selected CNVs in DMD, SMN1, or HBA1/2 genes (if included in panel)) within the scope are reported. Carrier status for autosomal recessive and X-linked recessive conditions is not reported.
