QDST^TM

QDST^TM, rapid tuberculosis Drug Susceptibility Testing

QDST is a rapid, phenotypic drug susceptibility testing system for tuberculosis. The system provides susceptibility test results for 15 drugs, including first and second line agents, in just a week, which can allow laboratories to shorten turnaround time by 3 to 5 weeks compared to the conventional test methods.

TB susceptibility results in 7 days
Random access with 120 sample capacity
Incubation for TB culture
Fully automated optical imaging to monitor bacterial growth
Algorithm based image analysis technology
S/R results based on critical concentration

QuantaMatrix's microbial diagnostics solutions are the first to be developed in Korea and have received the highest honors including the New Excellent Technology (NET) certification and new medical technology certification.

TB drug susceptibility test results in a week

QDST provides results of drug susceptibility test for tuberculosis in just 7 days. Compared to conventional test methods, which takes 4 to 6 weeks, QDST dramatically reduces time to results.

Treatment Decision Support

QMAC-DST^TM PLUS panel includes LNZ and Cs to help clinicians prescribe optimal treatment for patients with drug-resistance TB. Meanwhile, multi-concentration wells are available for INH, RIF, EMB, and Cs. High- and low-level resistance concentrations are provided in addition to the critical concentration, promoting better informed treatment decisions.

QDST Kit

QMAC-DST^TM PLUS kit offers a QMAC-DST^TM PLUS Panel together with panel sealer. The panel accommodates 4 primary and 11 secondary anti-TB drugs with multiple concentrations. In addition to the agarose that immobilizes the TB bacteria, the panel cover and panel sealer serve to ensure user safety.

1st line drugs

2nd line drugs

3-level safety system

The safety of the user is of utmost importance because tuberculosis is carried in airborne particles. QMAC-DST^TM PLUS Panel has a total of three levels of safety as shown below to prevent samples from leaking during the testing process.

Level 1

Immobilize TB bacteria in the agarose layer

Level 2

Seal the panel with panel sealer to prevent leakage of sample

Level 3

Lock the panel with the panel cover

QDST Workflow

STEP 1

Prepare mixture of cultured tuberculosis bacteria and agarose for immobilization.

STEP 2

Prepare mixture of cultured tuberculosis bacteria and agarose for immobilization.

STEP 3

Prepared panel is automatically loaded into 120 plate loaders in QDST.

STEP 4

Observation of bacterial growth and resistance to the drug within 7days through fully automated optical imaging.

STEP 5

Susceptibility results are reporting using proprietary algorithm and database based on critical concentration.

User-friendly interface

QDST^TM software utilizes a proprietary algorithm and database set to perform advanced drug susceptibility testing. Fully automated time-lapse imaging allows for highly precise measurement and calculation of micro-colony growth.
