ez-Tracker range associated with the ez-Track 1 instrument is a True Point-Of-Care solution for Therapeutic Drug Monitoring of Biologics

Fast and Simple

Using the ez-Track 1 will allow you to obtain reliable and accurate results for your biotherapy monitoring requests in 10 to 12 minutes depending on the parameter.


Usable with whole blood (capillary or venous), serum or even plasma, the flexibility of the ez-Tracker range will improve patient care.


Calibrated on the international standards (Infliximab and Adalimumab) of the WHO, the ez-Tracker kits offer excellent precision of the results. Time-Resolved Fluorescence technology provides high performance and very good correlation with i-Tracker and LISA TRACKER reference kits.

Time-Resolved Fluorescence - The principle

Time-resolved fluorescence (TRF) allows the measurement of fluorescence intensity. TRF uses a lanthanide fluorophore, such as europium. The latter emits a long fluorescence, of the order of a millisecond (conventional fluorophore emission ~ nanosecond). Therefore, excitation of the fluorophore by a pulsed light source, followed by a delay, then measurement of the signal called a “counting window”, allows the brief fluorescence (lasting only a few nanoseconds) to fade before to perform a measurement. Assays using time-resolved fluorescence achieve significantly higher signal-to-noise ratios.
