Single-Tube Saliva Collection: A Step-by-Step Guide

Collecting a saliva sample at home is straightforward when you follow the kit directions in order. This guide summarises the Single-Tube Saliva Collection Instructions. Always check the instructions supplied with your own kit and test panel, as collection requirements can vary.

Before choosing your collection day

First, check the test code and panel requirements on your requisition form. The guide says men, children and non-menstruating women can collect on any day of the month. If your cycle or test kit calls for specific timing, follow the full kit instructions or ask the laboratory.

If you use hormones, list them on the requisition form and continue them as prescribed. The guide also recommends changing sheets, pillowcases and towels the night before, and avoiding contact with bathroom surfaces that may have hormone residue.

Prepare ahead

• Three days before: the guide advises avoiding anti-ageing or anti-wrinkle facial creams and biotin (vitamin B7) products, including some hair and nail formulas. If any product is prescribed or medically advised, check with your healthcare professional or the laboratory before changing its use.
• The night before: stay normally hydrated and avoid excessive fluid intake.
• On collection morning: before collecting, do not eat, drink anything other than water, or brush your teeth. Begin collecting within 30 minutes of waking.

Collect and label the sample

1. Let saliva pool in your mouth, then transfer it into the tube.
2. Fill the tube at least halfway, not counting bubbles. The guide says collection usually takes 15–30 minutes, depending on saliva flow. If bubbles are filling the tube, gently tap it on a hard surface as the instructions suggest.
3. Screw the cap on securely. Write your name, collection date and collection time on the tube label, then place the tube in its bag.

Pack and return your kit

Complete the requisition form and any additional paperwork. Put the sample and completed documents back into the test kit box, include payment if applicable, close the box and place it in the return packaging. Add the prepaid label or postage if required, then use the carrier specified for your kit.
