DIAGNOSTICS OF COVID-19 USING A NEWLY DEVELOPED TEST - AUMED test RT-LAMP Assay SARS-CoV-2

AUMED a.s. is involved in the fight against the Covid-19 pandemic. In cooperation with Protean s.r.o. and Institute of Molecular and Translational Medicine, AUMED a.s. launched a modern diagnostics of SARS-CoV-2 virus under the name AUMED test RT-LAMP Assay SARS-CoV-2. It is a diagnostic using the RT - LAMP Assay method. The test uses the so-called LAMP reaction, which is isothermal amplification of nucleic acids. Unlike the polymerase chain reaction (PCR, qPCR), in which the reaction is performed using temperature cycles, isothermal amplification is performed at a constant temperature so there is no require for any expensive equipment. The results are reliably read based on the color change with the naked eye.

WHY LAMP REACTION?

Molecular amplification technique RT-LAMP (Reverse transcription - Loop mediated isothermal amplification) allows the amplification of nucleic acids with high specificity, efficiency and speed under isothermal conditions - i.e. at a constant temperature, achievable in incubators, hybridization ovens or dryers.

Main advantages of AUMED test RT - LAMP Assay SARS-CoV-2:

No need for expensive laboratory equipment - can be performed in any laboratory, no PCR cycler required.

• Results are available within one hour - the possibility of reading with the naked eye.

• Hundreds of samples can be analyzed at once.

Reduced costs compared to conventional PCR tests with the same sensitivity and reliability.

• The entire test can be performed in a small or mobile laboratory, possibly connected directly to the sampling site.

• Ideal solution for airport terminals, large companies, border crossings, homes for the elderly...

• The use of natural amplification enzymes guarantees high reliability of the test results, so that even if the incubation time is accidentally exceeded, false positive results do not occur. Competitive LAMP assays that use genetically engineered enzymes with higher processivity suffer from this problem. These tests are slightly faster, but there is a risk of false positive results.


DIAGNOSTIC KIT

The kit is fully validated and registered by the State Institute for Drug Control (SÚKL) under registration number 00912050 (issued by SIDC-CZ). Instructions and a valid declaration of conformity can be downloaded from the appendix of this registration. It is a completely Czech product without dependence on foreign suppliers.
The kit is intended for diagnosis of the presence of SARS-CoV-2 virus in isolated viral RNA samples - for 45 samples. The diagnostic kit involves the detection of SARS-CoV2 virus and the detection of an internal control (IC) to check the correct collection and processing of the sample.
The functional evaluation was successfully performed by the Institute of Molecular and Translational Medicine in Olomouc. Comparison of the kit with the reference RT-PCR assay determined the sensitivity of the assay to be 93% and specificity to 99%. The kit passed all tested parameters and was recommended for use.
Test sensitivity:
• Equivalent sensitivity with qPCR up to Ct 36-38
• Corresponds to 10 copies of virus per ul sample

Kit contents:

• A bag containing a 96-hole PCR plate and a plate of colored caps in a light-tight package. Should be stored at room temperature, caps in the original light-tight package or in the dark.

• Reagent box for 45 tests

IC = internal control; PC = positive control

Material required - not supplied with the kit:

• Automatic and multichannel pipettes

• Appropriate reservoir for the reaction mixture

• Pipette tips with RNAse and DNAse free aerosol filters

• Plate incubation device at 63 °C

NEW SAMPLING SYSTEM

AUMED, a.s. collaborated on the development of a new self-sampling set based on the principle of gargling of the oral cavity and pharynx. The new sampling set was named GARGTEST and was developed in cooperation with Institute of Molecular and Translational Medicine in Olomouc.

The new collection is therefore much more pleasant and completely painless. Instead of pushing the sticks into the nose, it is enough to gargle a sip of ordinary water for 20-30 seconds and then empty this content from the mouth into the enclosed collection container containing the transport powder. The user then closes the tube and packs it according to the instructions. The user will perform this procedure either at the sampling point or at home, from where he will then deliver the sample to the sampling point, to the laboratory or, for example, to his doctor.

The combination of the new GARGTEST sampling set and the AUMED test RT-LAMP Assay SARS-CoV-2 test kit creates completely new possibilities for the detection of new coronavirus in the population. Painless and fast collection without queues is followed by fast and reliable diagnostics!
