Blood test instructions

Step-by-step instructions for taking an at-home sample.

Important details before you take your blood sample

Taking a blood test from home is relatively simple, but we’ve put together some instructions to prevent errors and ensure the process runs smoothly. Before you get started, either give this page a read or watch our blood test kit tutorial video.

1
Take the test between Monday and Thursday only (so that there are no delays in getting it to the lab).
2
If your panel includes testosterone, please ensure to take the test before 11am ensuring that you've fasted at least 8 hours.
3
Drink two glasses of water within the 30 minutes before the test.
4
Post your sample shortly after drawing your blood. This helps provide a more accurate reading.

How to collect your blood sample

Instructions for test kits with 1x Tasso+ device

Please note that the Tasso+ device is single-use. After you attach it to your upper arm and press the red button, you might not feel the needle or see immediate blood flow - but don't worry, it's working. That's the magic of Tasso - it's virtually painless. Keep it attached until blood reaches the top fill line, as it cannot be reused once removed.

1
Lay your kit out on a low table, so you can stand and have your hand below your elbow – gravity helps your blood flow.
2
Wash your hands with soap and warm water.
3
On the upper section of your non-dominant arm, rub up and down for 2 minutes, Prepare the shoulder by using the alcohol swab to wipe the contact area. Ensure the shoulder is dry before attaching the Tasso+ device.
4
Remove the Tasso+ device from the tray.
5
Open the blood collection tube by twisting off the lid.
6
With fill lines facing out, press the blood collection tube into the Tasso+ device until snug.
7
Peel tab and clear cover from the red button on the Tasso+ device.
8
Stick the Tasso+ device to the shoulder and press the button until it clicks to start collection.

Allow tube to fill. Remove the Tasso+ device if blood reaches the top fill line before 5 minutes pass.
10
Remove the Tasso+ device by peeling from one side.
11
Remove the blood collection tube from the Tasso+ device with a slight twist and pull down. Replace the cap on the blood collection tube by pressing firmly until you hear it click.
12
Apply pressure to the shoulder with the sterile dry swab to stop the bleeding, wash hands and apply a plaster. Gently invert the tube at least 10 times but do not shake.
13

14
Place the transportation tube into the pathoseal bag and seal by removing the metallic silver strip.
