Take the sample 2–3 days before your scheduled courier pickup.

Do not take it if

On antibiotics

Step-by-step

1

Empty your bladder first

The sample must not be contaminated with urine.
2

Keep the sample clean

Avoid any contact with urine or toilet water.
3

Open the purple cap only

Don't open the yellow cap — it holds the preservative liquid.
4

Place a pea-sized sample on the X

Just rest it on the spoon's tip — don't push it inside.
5

Close & shake for 1 minute

Close the purple cap firmly, then shake so the liquid mixes in.
6

Store at room temperature

Stable for several weeks — no fridge or freezer needed.
