DNA GUIDE · DUBAI
DNA sample collection and laboratory process
DNA testing may use a cheek swab, saliva, blood or another validated sample. The correct choice and preparation come from the provider or laboratory. Identity, consent, labelling, transport and quality checks are as important as the collection itself.
How should you prepare for collection?
Follow only the instructions for the exact kit or appointment. Confirm eating, drinking or mouth-care restrictions, medicines, identification, consent documents and whether each participant attends together.
- Read the kit-specific preparation window
- Do not substitute containers, swabs or labels
- Bring the requested identity and consent documents
- Tell the provider about a recent transfusion, transplant or other factor they ask about
- Confirm whether collection must be witnessed
What should the collection pathway include?
A traceable pathway links the person, consent, request, sample, transport, analysis and report. If the sample is insufficient or contaminated, recollection may be safer than forcing a result.
Identity and consent
Confirm participants, authority to consent, intended use and result recipient.
Correct collection
Use the supplied materials and follow timing and handling instructions.
Label and seal
Check identifiers before the sample leaves your sight.
Transport and accession
The laboratory logs receipt and assesses sample acceptability.
Analysis and quality review
The validated method produces data that are reviewed before reporting.
What should you confirm after collection?
Keep the reference number, expected communication route and contact point. Ask what happens if the sample is delayed or rejected and how the provider verifies identity before releasing a report.
Answers before you decide.
Frequently asked questions
Does DNA collection hurt?
A cheek swab or saliva collection is generally non-invasive; blood collection involves a needle. The required sample depends on the validated test.
Can I use my own cotton swab?
No. Use only the collection device, packaging and labels supplied or approved for the test.
