What it is

You partner with accredited DNA testing labs and collect cheek swab samples from the people being tested. You verify IDs, take photos, complete the paperwork and ship samples to the lab. The lab does the testing, and you can offer legal-grade collections that need a neutral third party.

Your first three steps

  1. Contact several accredited DNA labs and ask about their collector or partner programs, training and requirements
  2. Set up an LLC or sole proprietorship, get general liability insurance, and build a collection kit and simple intake forms
  3. Introduce yourself to local family law attorneys and mediators, and list your service online with your service area
Who pays

Individuals and families, family law attorneys, and sometimes immigration or adoption-related clients. Some labs pay collectors a fee per collection, and you can also charge clients directly.

How it makes money

A fee per collection appointment, often with a travel or after-hours surcharge. You may also earn a referral fee or a share from partner labs, depending on the agreement.

Skills that help
  • Careful with paperwork and procedure
  • Calm, respectful and discreet with sensitive family situations
  • Reliable scheduling and travel planning
Watch out for
  • Check which tests qualify as legal or court-admissible and what chain-of-custody steps your partner labs require
  • Check your state and local rules on collecting samples, consent and privacy, including how to handle tests involving minors
  • General liability insurance, and ask an insurance agent whether you need professional liability too
  • Emotional and sometimes tense situations. Stay neutral and never give legal advice or share results
