Mitochondrial Species Identification

Increased awareness among consumers concerning food safety and security has prompted a significant increase in the need to verify food product fidelity. As consumer choice is often greatly influenced by food composition as indicated by product labelling, particularly in the meat industry, the accuracy of this information is of great importance. For the purpose of verifying the presence or absence of a particular species in food, mitochondrial DNA (mtDNA) is often used. Unlike nuclear DNA (nDNA), mtDNA is only inherited maternally, and is therefore significantly less diverse in its composition. As such, while mtDNA cannot be used to distinguish between individuals of the same species, it is far more effective at distinguishing between different species. At present, Unistel Medical Laboratories offers mitochondrial species identification for the following species:

  • Bovine
  • Fish
  • Equine
  • Chicken
  • Buffalo
  • Ovine
  • Porcine
  • Ostrich
  • Canine

Sample requirements:

For mitochondrial testing, the sample of choice is meat.

Dear valued supporters and suppliers

As the total effect of the COVID-19 lockdown becomes clear and the knock-on effect of this action is realized, Unistel Medical Laboratories has pro-actively put procedures in place to firstly ensure the absolute safety of staff and secondly to ensure the seamless continued functioning of the laboratory to provide essential diagnostic testing. No patient services, cytogenetic, Fluorescence in Situ Hybridization (FISH) and DNA testing can or will be compromised as this is an essential critical service. Staff will ensure services continue by working in non-overlapping shifts, keep social distance and completing as much analysis and reporting work electronically from home.

Unistel Medical Laboratories is committed to the huge effort to restrict the spread of COVID-19, but will also continue to provide essential world-class diagnostic and DNA testing services.

The veterinary diagnostic services will be continued on the same basis.

As all supporters will realize the turn-around time for results may be compromised slightly, but rest assured, Unistel Medical Laboratories will still do our level best to maintain timely service.
