SARS-CoV-2 RNA detection from saliva .
To determine whether SARS-CoV-2 RNA can be reliably detected in saliva samples collected with OMNIgene-ORAL (OME-505) stored at room temperature, stability tests were performed on samples from 15 participants using an internally verified RUO assay optimized for the detection of SARS-CoV-2 RNA in saliva. Samples were spiked with heat-inactivated SARS-CoV-2 at two different concentrations depicting a low viral spike (500 cp/mL) and a high viral spike (2,500 cp/mL). Samples were stored at room temperature (23 ± 3°C) for 21 days and extracted at baseline and at the 7 and 21 day time points. The SARS-CoV-2 nucleocapsid gene (N1 and N2) was used to detect the stability of viral RNA by RT-qPCR. Samples with a cq value of <40 had detectable viral RNA. The human RNase P gene (RP) was included as a control for human nucleic acid detection.
Cq values for SARS-CoV-2 RT-qPCR targets N1, N2 (viral), and RNase P (human, RP) at day 0 (purple), day 7 (blue), and day 21 (orange) in low-positive (500 cp/ml, N = 15) and high-positive (2,500 cp/ml, N = 14) enriched saliva samples. The dotted line indicates the detection limit. If no amplification was detected, the cq was set to 45 (maximum cq) for visualization. Statistical significance was determined using a two-way ANOVA with Sidak test for multiple comparisons.

Colli-Pee® FV-5000 .
Colli-Pee® is a patented sampling device that allows volumetric and standardized collection of morning urine. The product range consists of variants that collect different volumes from 4 to 45 mL. The collection tubes can be pre-filled with a preservative, allowing for longer storage and/or shipment of urine at room temperature.
First urine contains higher concentrations of analytes associated with various sexually transmitted infections, including human papillomavirus (HPV) and Chlamydia trachomatis (CT) DNA. In addition, the collection of urine samples from the morning first stream is important for the identification of cancer biomarkers, e.g., for prostate cancer.
- Easy to use for both men and women
- Can be shipped to individuals as well as laboratories for testing purposes
- Sampling at home possible
- Optional: filling of Colli-Pee® with Novosanis' urine preservation medium (UCM) to preserve the DNA in the urine
