The Dimex is a two channel optical instrument designed for the quantitative determination of a D-Dimer. The test procedure is optimized for easy handling and quick turnaround time. The accurate and precise results are reported in µg/mL or ng/mL.

The priciple of detection is based on the agglutination of D-Dimer antigen in the assay sample, with D-Dimer monoclonal antibody coated latex particles. The rate of agglutination is proportional to the decrease in transmitted laser light.

The Dimex utilizes a unique modified kinetic algorithem, which eliminates false results caused by the "Heidelberg-Effect". In addition, results are available after 80 seconds. Further, either duplicate or single measurements can be made. The new created double-micro cuvette allows an effective work, even for more samples.

Pipetting scheme:

25 µL Plasma (sample)
+ 50 µL Reaction Buffer
+ 50 µL Latex
The Dimex is perfectly suitable for all laboratories, as well as Emergency Rooms, Clinics and physician office laboratories.

Tests:
Quantitative D-Dimer (other tests under development)

Assay range for sample concentrations
50-8.000 ng/mL (undiluted plasma)
>8.000 ng/mL (1:10 pre-dilution of sample)

Selectable dimensions
dE/min, µg/mL, ng/mL

Coefficient of Variation (CV - with TECO reagents)
at 200 ng/mL: <10%; at 1000 ng/mL: <7%; at 2000ng/mL: <5%

MORE INFORMATION

Technical Description

The Dimex is a micro-computer controled Coagulation instrument with two channels and a LC-Display. The tests will be selected through keys on a foil keyboard. The dialog language is user friendly and selectable in English and German. Other languages can be provided optionally.

The Main program offers the following menus:

ANALYSIS
CALIBRATION
SYSTEM
SERVICE

The measurement can be started manually by pressing the OPTIC-key in the same time when reagent is added or with a connected Autopipette. The results are displayed in the measured dimension and can be converted into other desired dimensions by pressing the UNIT-key. A connected printer will automatically print out the results in all dimensions with Optic channel and test name. The patient identification No. (PID) can be optionally selected between:

NO PAT.ID
MANUAL ENTRY
AUTO-SERIES with Start No.

Using the TECO Softwaretools the measuring curve data can be transmitted to a Persoanl Computer and loaded by any spreadsheet with graphic function. Software updayes are realized with an easy download from a computer to the instrument.
