Guava Technologies has announced a complete turnkey package for CD4 monitoring that requires minimum technical expertise to operate and obtain high quality results
Comprising an optimised, integrated package of reagents, software and instrumentation the Guava Auto CD4/CD4% System was designed to provide developing countries with a simple, easy-to-use tool to help fight the global Aids pandemic.
By providing values for both CD4 and CD4% of total lymphocytes, the assay is applicable to both adult and paediatric samples.
The Guava Auto CD4/CD4% assay with an easy-to-use reagent kit provides CD4 counts, total lymphocyte counts, and CD4% values in one simple assay.
The new assay employs a premade cocktail, and only 10ul of whole blood in a simple two-step, no wash protocol that requires minimal technical expertise to perform efficiently and accurately - saving users both time and money.
The automated adjust settings, acquisition and gating features in the new Guava Auto CD4/CD4% software module speed reproducible generation of high quality test results.
Combining these automated features with easy-to-read result screens, individual patient reports, summary reports and automated error detection facilitate productive use of the system.
Testing on normal and HIV adult and paediatric samples using the Auto CD4/CD4% assay provided accurate test results when compared to traditional clinical lab results.
Excellent precision (CV <10%) was also obtained across multiple CD4% and CD4 count ranges.
Mat Taylor, European marketing manager commented "The combination of a new reagent cocktail with automated software should extend the use of the Auto CD4/CD4% Assay to users with minimal or no cytometry experience.
"The Auto CD4/CD4% system is based on Guava's proprietary micro-capillary cytometry technology.
"This enabling technology provides our customers with reliable and robust measurements using smaller sample volumes than any other system on the market".
"Moreover, as micro-capillary cytometry technology does not require the use of sheath fluid, daily maintenance of the system is minimal".
