TUBEX® TF

Rapid Typhoid Detection.

IDL Diagnostics TUBEX® TF is a rapid and sensitive in vitro diagnostic test for the detection of acute typhoid fever, a disease caused by Salmonella typhi.

TUBEX® TF

TUBEX® TF can easily be performed in any laboratory or field setting, and with a result within 10 minutes. A positive TUBEX® TF result, together with typical clinical symptoms, is a strong indication of acute typhoid fever.

The test is a semiquantitative assay based on IMBI® technology (Inhibition Magnetic Binding Immunoassay), a simple assay technology based on visual interpretation.

A complement product to TUBEX® TF is TUBEX® TF Wash which is recommended to be used for the analysis of colored serum samples.

IDL Biotech is the legal manufacturer of TUBEX® TF and TUBEX® TF Wash.

Clinical evaluation

In a comparative study in the Philippines, Kawano and co-workers evaluated four antibody detection tests for typhoid fever. The sensitivity of TUBEX® TF was 95% at a specificity of 80%. In this study TUBEX® TF performed best among other analysed tests. TUBEX® TF has been clinically evaluated on more than 5000 patients in different endemic settings, showing consistent performance across multiple continents.
