IMDNA provides ongoing scientific, technical, and non-regulatory support for laboratories that need continued assistance after an assay, instrument, workflow, or method has been implemented. Support can include technical consultations, assay-performance review, QC and reference-material support, reagent and lot-change review, troubleshooting, method updates, comparison or bridging studies, workflow optimization, training resources, documentation support, instrument-related technical coordination, and continuous performance improvement.
Laboratory systems evolve over time. Reagent lots change, instruments are serviced or replaced, operators change, sample volume increases, workflows are revised, methods are transferred, and new technical questions emerge. IMDNA can provide continuity across these changes by helping the laboratory evaluate technical impact, organize supporting studies, troubleshoot performance, update documentation, and maintain practical scientific knowledge around the method.
Implementation is not the end of an assay or laboratory workflow lifecycle. CMS quality resources address ongoing laboratory operations, quality control, performance verification, calibration, proficiency testing, and personnel competency. NIH/NCATS similarly treats robust assay performance as a lifecycle process that includes optimization, data analysis, assay artifacts, instrumentation, and operational rigor. IMDNA's ongoing support model is designed around that continuing technical reality.

Assist when reagents, lots, instruments, software, sample preparation, workflow, or other method components change.
Provide scientific support when unexpected control, reagent, instrument, sample, or method-performance issues arise.
Preserve technical understanding through staff changes, method updates, training needs, and evolving laboratory operations.
Use quality data, technical observations, and workflow experience to identify practical opportunities for improvement.
Support can be structured as project-based assistance, periodic technical review, issue-driven support, or an ongoing scientific relationship depending on the laboratory's needs.
Provide access to IMDNA's scientific and technical team for assay, reagent, workflow, instrument, data, sample, control, or method-related questions.

Support addition of targets, sample types, panels, biomarkers, technologies, or other scientifically justified method extensions.
Maintain technical continuity when personnel change or additional team members begin supporting the method.
Keep technical documents aligned with the method as reagents, workflow, troubleshooting knowledge, and operating practices evolve.
Technical support is strongest when performance trends are reviewed before a small change becomes a recurring problem. The specific indicators depend on the method and laboratory.
| Technical Area | Examples of What May Be Reviewed | Potential IMDNA Support |
|---|---|---|
| Controls | Shifts, trends, failed controls, increased variability, changes after lot replacement, unexpected background. | Trend review, lot comparison, troubleshooting plan, QC/reference-material support. |
| Assay Performance | Sensitivity, specificity, precision, signal intensity, efficiency, dynamic range, recovery, agreement, false signal. | Performance review, focused studies, optimization, technical data analysis. |
| Instrument Performance | Service events, calibration-related changes, detector/optical behavior, fluidics, software updates, acquisition changes. | Before/after comparison, manufacturer/service coordination support, technical impact review. |
| Reagents & Lots | New lot, supplier change, reagent age, storage, stability, preparation, altered signal or response. | Lot bridging, side-by-side comparison, reference-material challenge, troubleshooting. |
| Sample / Matrix | New sample type, altered extraction, inhibition, degradation, matrix effect, sample-storage changes. | Matrix comparison, dilution/inhibition study, extraction review, technical optimization. |
| Workflow | Batching, timing, sample routing, staff changes, plate setup, washing, pipetting, data review. | Workflow mapping, retraining resources, optimization, process documentation. |
Not every laboratory change has the same technical impact. IMDNA can help laboratories identify which changes may warrant documentation, comparison, bridging, troubleshooting, retraining, or broader study.
Ongoing support can include maintaining the scientific and operational knowledge around the method as it changes.
Different assay technologies develop different operational issues over time. IMDNA can tailor ongoing technical support within its scientific expertise.
