Designed for simple, safe, and stable COVID-19 specimen collection

LabTurbo™  Specimen Collection Kit

The LabTurbo Nasopharyngeal Swab Collection and Transportation Kit (LS0610) is intended for the collection and transportation of nasopharyngeal specimen for nucleic acid testing. The nylon-flocked swab provides the wide-ranging, simple and pain-free sampling for patients to collect nasopharyngeal swab specimens. The virus and microorganism on the collected sample is inactivated in the provided transportation medium. And the collection kit can be shipped at room temperature. The nucleic acid is stabilized in the transportation medium for good nucleic acid integrity and consistent test gin results.

RESULTS AND PERFORMANCE

Transportation Stabilty Test

A series of various temperatures were used to simulate the temperature change during regular shippimg condition. The transportation medium with spiked SARS-CoV-2 virus at 2000 copies/ml, 4000 copies/ml and 8000 copies/ml and negative samples were used to evaluate the preservation performance of the LabTurbo LS0609 after the transportation simulation cycle.

All the samples at 2000 copies/ml, 4000 copies/ml and 8000 copies/ml were detected after the shipping simulation cycle, indicating good preservative performance of LabTurbo LS0609 during various shipping conditions.

Preservation Stabilty Test

To validate the preservation performance of LabTurbo LS0609, the high and low spiked SARS-CoV-2 positive specimens were extracted and detected by qPCR right after specimen preparation (Hour 0). The prepared high and low positive specimens were incubated at 37 °C in for 150 hours in total. The high and low positive specimens were extracted and detected by qPCR at Hour 50 and Hour 150 to confirm the preservation of SARS-CoV-2 RNA.

High Positive Low Positive
Replicate 1 2 3 1 2 3
Hour 0 25.31 25.27 25.34 27.99 28.47 28.31
Hour 50 25.25 25.54 25.66 28.50 28.65 28.22
Hour 150 25.15 25.46 25.50 28.51 28.77 28.31

No significant difference was found between Hour 0, Hour 50, Hour 150, indicating good preservation performance of LabTurbo LS0609.
