Should you require any other analytical support, our multidisciplinary analytical team offers clients a customisable service to test something unusual, confirm a hunch, bridge a gap or simply offer peace of mind.
|Test results may be generated by FACTS or a laboratory competent in performing the requested analysis.|
When the analysis is #facilitated, FACTS provides the following services where applicable or as per instruction from the client:
• Sourcing an appropriate laboratory for sample matrix and objective of analyses.
• Coordinating sample distribution and analyses.
• Interpretation of results are in the context of the relevant South African regulations where applicable, with guidance documents, standards, or scientific literature.
• Presentation of results, background information and interpretations in an easy-to-understand report.
The lead times for facilitated testing is subject to change and may be altered by number of samples and laboratory capacity.
FACTS SAMPLING KITS
FACTS supply below sampling kits for allergen control validation purposes. The intent is that samples are submitted to the FACTS laboratory for analyses.
|FACTS Environmental Surface swab kit||The kit provides all the materials required for the collection of a surface swab sample for the detection of allergenic residues by means of ELISA or PCR.|
|FACTS Air plates||The passive aerial allergen contamination estimation kit provides all the materials required for the collection of environmental dust samples, from which the content of allergenic cross contamination can be estimated.|
RAPID TESTING KITS
FACTS sell a variety of rapid testing kits that detect e.g. food allergens and meat species. These kits are ideal for on-site verification and screening activities and can be used to test e.g. rinse water, surface swabs, ingredients and finished products.
It is important to note that when using a rapid kit for ingredient and product testing it must be ensured that the system is validated for the specific ingredient / product. Contact us if you need assistance with such validation studies.
