BioAssay Lab COVID-19 status:

Due to the current Covid-19 outbreak, we will not be taking any new requests for analyses at this time and all current orders have been halted until further notice. Please check back here regularly for the most recent updates.

Precautions against the COVID-19 virus at the BioAssay Lab

SALIVA/BLOOD SAMPLES:

In the interest of safety for our staff, and to mitigate the spread of COVID-19, the BioAssay Lab will not accept saliva nor blood samples that are at risk of being infected. Due to the variable incubation time frame of the virus, any samples collected three weeks prior to the first reported infection in the province of collection will not be tested at this facility.

 

Quebec: All samples collected after February 7th, 2020 will not be tested.

British Colombia: All samples collected after January 7th, 2020 will not be tested.

Ontario: All samples collected after January 2nd, 2020 will not be tested.

*For all other provinces and countries outside Canada, please contact us for dates.

 

Samples collected after these dates should not be sent to the BioAssay Lab and should be separated from the remaining samples before shipping.

 

The responsibility to ensure that we do not receive samples infected with the COVID-19 virus rests with the researcher, who will be requested to sign a document taking legal responsibility for the samples.

 

HAIR SAMPLES:

Hair samples will be accepted for analysis provided that they were collected following the procedure on our website and after some precautionary measures.

1. The researcher will wait 14 days after gathering hair samples before sending them to the BioAssay lab.
2. The BioAssay lab will wait another 14 days before starting the preparation for the hair analysis.

 

The time frames for collection may change as new data emerges about the virus. Thank you for your cooperation and understanding.

CSHS BioAssay Lab

THROUGH a grant from the canadian FOUNDATION for innovation, the Centre for Studies on Human Stress  has established a laboratory for  THE ANALYSIS OF various stress-related hormones in humans.

The laboratory can also STORE samples in the biobank, at the request of researchers, and with the approval of ethics boards.

FOR RESEARCHERS in Quebec, it is advantageous to have hair and saliva samples obtained from scientific studies analyzed here in a Quebec laboratory.  This way, it is unnecessary to ship samples to the United States or other countries, as this could entail various risks including samples being held at customs, poor handling and loss of samples during shipment.

COST OF ANALYSIS at the CSHS BioAssay Lab is highly competitive. The lab also provides freezer storage for researchers who wish to retain remnants of saliva or blood from their studies, that were not used during analysis. A consent form must be signed by participants in order for researchers to conserve the remaining samples in the biobank. The CSHS provides information on this consent procedure, as well as examples of consent forms concerning saliva or blood banks.

The laboratory has recently introduced the analysis of cortisol in hair samples, and has validated the method with an international laboratory.

Since 2011, the Centre has provided services of salivary hormone analysis, most frequently measured in studies on human stress, including cortisol and sex hormones.
The CSHS also provides information needed on the methodology used to take hair or saliva samples, for cortisol and other stress-related hormone analysis.

Our salivary analyses are performed by qualified and competent personnel, and are validated annually by our supplier, Salimetrics. Our facilities are at the forefront of technology. Our freezers are equipped with alarms and we ensure continuous high-quality service. We offer -20 and -80 Celsius freezer storage.
