Procedure: 5-easy steps with no specimen pretreatment
The 2 year shelf life and room temperature storage ensures no reagents are wasted. Also, the moderate complexity CLIA rating allows for cryptococcal antigen testing to be easily offered on all laboratory shifts, on a STAT basis, and as a Point-of-Care assay.
Key Advantages of the CrAg® LFA:
- 10 minute test time | 1 minute tech time
- No specimen Pretreatment
- No Boiling (CSF)
- No Pronase™/Protease™ (serum)
- 2 year shelf life | Room temperature storage | Condensed Packaging
- Internal Control line eliminates costly external control requirement
- Qualitative and semi-quantitative results
- As easy as a home pregnancy test
Semi-Quantitative (titer) Procedure
The IMMY CrAg® LFA offers rapid and cost effective semi-quantitative (titration) results, which may be requested following a positive cryptococcal antigen screen. The semi-quantitative procedure is similar to the traditional latex agglutination method, in that initial set-up requires preparation of two-fold serial dilutions. However, rather than preparing dilutions on a ring slide, they are set-up in individual tubes. In order to minimize the cost of performing the titer, many labs utilize the IMMY titration algorithm, which can be viewed by watching the video below:

Utilizing the IMMY CrAg® LFA for the titration procedure will not only yield the most sensitive and accurate results for positive patients, but positive samples can be screened and titration performed in about 20 minutes, a process that takes upward of two hours with traditional latex agglutination testing.
