Droplet Digital PCR provides highly sensitive absolute quantitation of DNA or RNA in serum, plasma, tissue or urine without the need of a standard curve. This is achieved by partitioning a sample into thousands of separate DNA or RNA molecules within nano-liter sized droplets. Each droplet can then be directly detected or quantified with unmatched sensitivity and precision.
With a fast turn-around time and low sample cost, Droplet Digital PCR is ideal for liquid biopsy applications including precise copy number analysis, sensitive rare mutation detection and accurate gene fusion quantitation. Droplet Digital PCR also works well for single-gene biomarker quantitation.

Next-Generation Sequencing Orthogonal Confirmation
Next-generation sequencing (NGS) has experienced rapid adoption by clinical laboratories for the simultaneous detection of multiple gene targets. With this expansion into clinical labs, especially for the use in molecular oncology, various organizations have published guidelines to ensure the accuracy and quality of NGS data used in patient care.
Recently, Droplet Digital PCR has emerged as the gold standard for NGS orthogonal testing due to the ability to precisely detect copy number variations and sensitively quantify variant allele frequencies.

Newborn Screening & Carrier Testing
The recent addition of Spinal Muscular Atrophy (SMA) to the Recommended Universal Screening Panel has highlighted the utility of Droplet Digital PCR laboratory developed tests (LDTs) for newborn screening.
SMA is an autosomal recessive disorder that is caused by deletions in the survival motor neuron gene 1 (SMN1) resulting in neurodegeneration and progressive muscle atrophy and ultimately respiratory failure. SMA disease severity is correlated with the individuals SMN2 gene copy state (ranging from 0-4+ copies).
It’s also important to note that the American College of Obstetricians and Gynecologists recommends that all pregnant women or those considering pregnancy should be offered screening for SMA.
The precision of Droplet Digital PCR makes it an ideal technology to accurately discriminate copy number states when compared to other molecular methods such as qPCR and NGS.
