What it is

You act as an independent sample collector for an accredited DNA laboratory. You meet the people being tested, check ID, take consent forms and cheek swabs, and keep a documented chain of custody. The lab does the testing and reports the results.

Your first three steps

  1. Contact several UK accredited DNA labs to ask if they use independent collectors and what training, checks and insurance they require
  2. Complete the lab's collector training, get an enhanced DBS check and arrange public liability and professional indemnity insurance
  3. Set up a simple website and introduce yourself to local family law solicitors and immigration advisers
Who pays

Individuals who need a witnessed test for legal, immigration or family reasons, plus solicitors and family law practices who need a reliable collector near the client.

How it makes money

A fee per appointment, often with extra for travel, evening or weekend visits and additional participants. Some labs pay you per collection, and some let you set your own price.

Skills that help
  • Calm, discreet and non-judgemental with sensitive family situations
  • Careful record-keeping and following procedures exactly
  • Reliable, punctual and happy to travel
Watch out for
  • Check the lab is accredited to the right standard and that its reports will be accepted for the purpose, such as court or Home Office use
  • Under the Human Tissue Act 2004, testing someone's DNA without proper consent can be an offence, so follow consent and ID procedures strictly
  • Check what insurance you need, including professional indemnity and public liability
  • Check the rules on handling and storing personal data with the ICO, including whether you need to register and pay the data protection fee
  • Emotionally sensitive work, including children and disputes, so keep clear boundaries and never give legal advice
