Case Study: Daktari Diagnostics achieves consistent, near‑lab accuracy for point-of-care CD4 testing with Quantrix

Daktari Uses Quantrix to Improve Healthcare Diagnostics

Daktari Diagnostics aimed to improve point-of-care CD4 cell counting for patients in resource-poor markets by ensuring its rapid, 15-minute CD4 device produced results within 10% of laboratory gold-standard values. To pinpoint why individual runs deviated, Daktari used Quantrix (including the DataLink import module) to ingest and organize the device’s >10,000 measurements per sample along with environmental and operator data for multidimensional analysis.

Using Quantrix, Daktari treated each run as a dimensional array, applied multiple formulas and visualizations, and rapidly isolated factors — such as room temperature or processing time — that drove variance from the gold standard. Quantrix’s drag-and-drop, multi-formula modeling let the team process large batches without rewriting formulas, accelerating root-cause analysis and device tuning and helping Daktari progress toward consistent results within its 10% accuracy target.
