The SalivaClear Solution

Mirimus has innovated high-volume COVID-19 PCR testing with SalivaClear, a three-stage testing strategy to monitor and detect infection in populations by testing people in groups called pools that can be reflexed to individual diagnostics tests upon positive pool detection.

All three-stages of testing are performed with only one self-collected saliva sample.


Monitor Population

Test your population in pools of up to 24 people at regular frequency to detect the presence of infection.

24 hours


Detect Hotspots

A detected positive pool is tested in smaller pools of 2 samples to isolate the infection to two people.

+ 12 hours


Reflex Test Individuals

A positive pool of 2 samples are reflex tested as 2 diagnostic tests to identify the infected individual.

+ 6 hours

Frequently Asked Questions

What is Mirimus SalivaClear?

SalivaClear is a three-stage testing protocol to monitor and detect SARS-CoV-2 infection in populations and identify infected individuals by testing people in groups called pools.

Stage 1: Test pools of up to 24 samples
Stage 2: Test positive pools in smaller subpools of 2 – 3 samples
Stage 3: Reflex positive subpool samples as individual diagnostic tests

What are SalivaClear result turnaround times?

Stage 1: 24 hours from receipt of samples at the lab
Stage 2: 12 additional hours from Stage 1 results
Stage 3: 6 additional hours from Stage 2 results

Is SalivaClear a PCR test?

Yes, SalivaClear is a real-time polymerase chain reaction (RT-PCR) test.

What is pool testing?

Pool testing means combining respiratory samples, such as saliva from several people and conducting one laboratory test on the combined pool of samples to detect SARS-CoV-2, the virus that causes COVID-19.

Why is pooling used?

Pooling allows Mirimus to test more samples with fewer testing materials and achieve faster result turnaround times.

What is your saliva sample collection method?

We use a simple self-collection method that is composed of a 2 mL cryogenics vial and saliva collection aid (straw).  The saliva straw fits into a cryogenic vial and the testing individual deposits 1 mL of saliva through the straw into the vial. 1 mL of saliva is required for pool testing, subpool testing, and individual diagnostic testing.

Is a saliva sample stable at room temperature?

Saliva samples are stable at room temperature without any buffer or refrigeration required for storage or transport.

What test system is used for SalivaClear testing?

Mirimus uses the Thermo Fisher TaqPath COVID-19 Combo Kit for pool and individual diagnostic testing. It is a fast, highly sensitive multiplex diagnostic solution that contains the assays and controls needed for the real-time PCR detection of RNA from the SARS-CoV-2 virus.

What is SalivaDirect?

SalivaDirect is a process developed at the Yale School of Public Health to test persons suspected of having COVID-19 for the virus, SARS-CoV-2. SalivaDirect received emergency use authorization (EUA) from the U.S. Food and Drug Administration on Aug. 15, 2020.

Yale has designated Mirimus as an authorized laboratory to provide SalivaDirect as a method for individual diagnostic testing.

What happens if the pooled test result is not detected (presumptively negative)?

If a pool test result is negative, then all the samples can be presumed negative with the single test. In other words, all the people who provided samples can be assumed to test negative for SARS-CoV-2 infection.

What happens if a pool test result is detected (positive)?

If a stage 1 pool test detects the presence of SARS-CoV-2 infection, the samples in the pool will be tested in smaller stage 2 subpools of 2 -3 samples. The positive stage 2 subpools will then be individually reflex tested as a diagnostic to identify the positive individual.
