Phases:
Items You Need Before Performing a Test
We've made it simple so you can do
the test from the comfort of your
home. Your subscription kit contains
everything you need to perform a
haemoglobin (Hb) test. Make sure you
read the instructions carefully.
01. Luma
To perform a measurement.
03. Lancet
To prick your nger.
It will be quick and easy and will
only take a couple of minutes.
02. Cuvee
To collect the blood sample.
04. Tissues
To wipe blood.

Things You Need to Know before You Do a Test
15
01. Time and position
Perform every test at the same
time and in the same position.
We recommend doing tests in the
morning, in a seated position.
02. Stay hydrated
It is recommended to drink 2 litres of
water a day. If you are dehydrated
your haemoglobin result will be higher
than it really is.
04. Warm your hands
By running them under warm water.
Having warm hands allows the blood
drop to form easily. Wearing a ring
and having cold hands can decrease
blood ow, which can aect results.
03. Dry your hands
If your hands are wet, the drop of
blood may be diluted which could
cause a false low reading.
05. Don’t squeeze
Allow the drop to form naturally. Don’t
squeeze your nger. Squeezing can
damage red blood cells, creating a
false result.
06. Below elbow level
To increase blood ow, you can
maintain your nger below elbow
level.
