PCR Home Sample Test Kits

  • Registering too early – Only register your URN/kit once the sample has been taken – legally we cannot change the sample collection date and time.
  • Not registering sample – All URNs/kits must be registered in order to receive a result. All kits must be registered individually AFTER sample has been taken.
  • Using the incorrect kit on the incorrect day – Ensure you check the label on the kit before use. Each kit has a specific prefix relating to each kit type therefore kits cannot be used for anything other than its intended use.
  • Not checking personal details at URN/kit registration – Please be sure to check all personal information before submitting your URN/kit registration. This information will appear on your certificate and cannot be changed so it is important it is correct.
  • Returning your PCR sample via Randox dropbox – It is the responsibility of the customer to check that Randox dropbox locations suit their needs before purchasing a test kit. For more information on how to return your sample visit https://covid.randox.com/kit-return/
  • Swab date and time entered incorrectly – Please ensure swab date and time is entered as UK GMT.
  • Not following instructions for use included in home sample test kit – Please be sure to carefully follow the instructions that are provided with the Home Sample test kits, and follow the procedures as required. Not following the correct procedures can mean that the sample will not be suitable for analysis with an UNCLEAR result provided. Examples of incorrect procedure include but are not limited to; not including the swab in the sample tube after swabbing, cap not adequately secured resulting in loss of buffer or removing the buffer from the sample tube. Both these examples are not within the procedures explained in the instructions within the home test kits. To confirm, failure to correctly follow the correct procedure may impact the sample suitability for analysis.
