Nasopharyngeal (NP) swabs are a preferred specimen type for optimal sensitivity (reference 1)

Nasal swabs, especially when used in the combined swabbing of Throat and both Nares when NP specimen cannot be collected, is a preferred specimen type among non NP-options (reference 1)

Saliva Collection kits Please contact us.

Viral Transport Media (VTMs)

VTM Type 1- Hanks Balanced Salt Solution-based on CDC SOP (reference 3), labelled and validated for sterility (reference 2) are one of the preferred transport medium types (references 1-5).  This type of media do not inactivate the viruses that may be present in the collected sample.

VTM Type 2: the Guanidium HCl based-VTM is equivalent to the transport medium from Cobas PCR Media Dual Swab Sample Packet, is another preferred transport medium type (references 1-5). This type of media inactivates the viruses and protects viral RNA that may be present in the collected sample.

  Individually wrapped swabs alone, or VTM alone or kits containing both swab and VTM from several qualified manufacturers are available.

Please talk to us re: technical and pricing information and arranging trial samples.
