How to find the right Clinical Diagnostic Test Kits AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Clinical Diagnostic Test Kits
- CLIA complexity
- Confirm the kit is CLIA-waived for the sample type you will use if you hold only a waiver certificate Waived status can apply to one specimen type and not another, for example nasal swab versus nasopharyngeal swab.
- Clinical performance
- Compare the package insert's sensitivity and specificity against the reference method, not marketing claims Rapid antigen tests vary widely in sensitivity, and low-sensitivity kits need confirmatory testing for negatives.
- Controls
- Prefer kits that include external positive and negative controls, and run them per the insert and your lab's QC policy External controls catch lot or storage failures that the internal control line cannot.
- Storage and shipping
- Check the required storage temperature range and how the seller ships Heat or freezing in transit can silently degrade immunoassay reagents.
- Intended use labeling
- Use kits labeled for in vitro diagnostic use, not research use only RUO kits are not validated for patient results.
Brands that matter
- QuidelOrtho: QuickVue and Sofia lines for strep, flu, hCG and other assays.
- Abbott: BinaxNOW rapid antigen tests and ID NOW molecular platform.
- BD: Veritor rapid antigen system with a digital reader.
- Sekisui Diagnostics: OSOM rapid test line.
- Siemens Healthineers: Urinalysis strips and point-of-care consumables.
What to avoid
- Research-use-only kits for patient diagnosis
- Kits with expiry dates that fall before you will use them
- Kits sold without the package insert or with unreadable lot information
- Using a kit with a specimen type it is not cleared for
Questions
Do waived kits still need quality control?
Yes. Follow the manufacturer's insert for control frequency, and run controls with each new lot or shipment as most labs require.
