One DNA microarray run. Many quality-assurance questions answered at once.
QAID is a system you run in your own laboratory. You prepare the sample, run it on a QAID microarray slide, scan the slide on a compatible microarray scanner, and analyze the data in the QAID App. QAID designs the microarrays, builds the software and the reference panels behind it, and trains your team to use them.
A DNA microarray is a slide carrying thousands of short DNA probes, each designed to bind DNA from one target. Because every probe is read in the same run, a single test can ask many questions at once instead of one question per tube.
After the sample has been prepared and run on the slide, your team scans it on a compatible microarray scanner. The scanner records the signal at every probe position and exports a data file. The sample and the data stay with you.
The QAID App applies the analysis workflow for the product the slide was run on: it checks the assay controls, measures each probe against the background on that slide, and reports which targets were identified, with confidence metrics behind every call.
Each product has its own curated reference panel: the targets it screens for and the probes that represent them. The panel is what turns a grid of signal values into a species name. How the reference library works.
From a sample on your bench to a decision your QA team can document.
Your raw material or finished product
A purpose-designed DNA microarray for your QA challenge
The slide is scanned in your own lab
Analysis and interpretation, with assay controls
Release, hold or investigate — your call, with the evidence
Conventional single-target methods answer one question per reaction. Screening a botanical blend or a seafood mixture against a long list of possible species therefore means running a long list of tests, and you only find what you thought to look for.
A microarray inverts that. The panel is decided when the product is designed, so every run screens for every target on it. You see the species you expected, the ones you did not, and the ones that were screened for and not detected — which is often the more useful half of the answer.
QAID supplies the system. The microarray products, the QAID App, the reference panels and the training to implement them.
You run it, and you decide. The run happens in your laboratory, the results stay private to your organization, and release, hold, retest or confirmatory testing remains your call. How QAID products are validated and what you need to get started.
