<h2>What are PCR and molecular assays for microbiomics?</h2>
&nbsp;
PCR and molecular assays in this category use quantitative PCR (qPCR) or digital PCR to measure the copy number of a defined DNA target, most often the 16S rRNA gene, to determine total bacterial load in a sample, or a specific pathogen or functional gene target for detection purposes. Unlike 16S or shotgun sequencing, which characterize the full taxonomic or functional composition of a community, these molecular assays provide a faster, more targeted quantitative or presence/absence readout for a specific question.

<h2>How to choose PCR and molecular assays</h2>
&nbsp;
Use total bacterial load qPCR to screen samples before sequencing
A qPCR assay targeting the 16S rRNA gene quantifies total bacterial content in a sample, providing a useful pre-sequencing check for low-biomass samples likely to produce poor amplification or unreliable sequencing results if processed without this screening step.
Decide between qPCR and digital PCR based on sensitivity needs
Digital PCR can offer higher sensitivity and more accurate quantification than standard qPCR, particularly for low-biomass samples at the limit of detection, though at the cost of longer processing time, generally a meaningful tradeoff only when standard qPCR proves insufficient.
Confirm your qPCR assay design addresses known technical pitfalls
Well-designed 16S qPCR assays address known issues like self-priming or mispriming of unintended targets, amplification bias from non-optimal primer coverage, and amplicon size constraints for compatibility with clinical or high-throughput qPCR platforms.
Use pathogen-specific or functional gene qPCR for targeted detection
Beyond total bacterial load, qPCR can target a specific pathogen's single-copy gene or a functional gene of interest, such as an antibiotic resistance gene, providing a faster, more targeted answer than waiting for full sequencing and bioinformatic analysis.
Plan for known PCR limitations in environmental and clinical samples
Standard qPCR can be limited by reliance on standard reference materials for quantification and is prone to inhibition from substances naturally present in environmental or clinical samples, such as heavy metals or organic matter, which digital PCR can sometimes overcome with improved robustness.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
A PCR-based total bacterial quantification assay can provide an exact calculation of bacterial abundance useful for assessing whether a sample is likely to yield positive amplification before committing it to full sequencing, helping avoid wasted sequencing runs on low-biomass samples. As of 2026, digital PCR continues to see increased adoption over standard qPCR specifically for low-biomass, environmental, or inhibitor-prone sample types, where its improved sensitivity and accuracy can outweigh its longer processing time.
