HealthcheX CHO– What does it do?
The HealthcheX CHO test is a self assessment test to detect,
in vitro, the concentration of total cholesterol in a blood sample
obtained from a single finger prick. The kit contains one test
in a sealed foil marked “HealthcheX CHO”; for assessing total
cholesterol in whole blood sample only.
About Cholesterol
Cholesterol is a greasy substance, mainly produced in the
liver. The body also absorbs cholesterol from food. Cholesterol
is encapsulated by proteins and transported by blood. The
body needs cholesterol to produce certain cells, hormones
and for digestion. There are two major kinds of cholesterol:
LDL-cholesterol (low-density lipo-protein) and HDL-cholesterol
(high-density lipo-protein). LDL-cholesterol, also called “bad” cholesterol, may lead to “arteriosclerosis” or coating of the
inside of the blood vessels which can lead to cardiovascular
problems. HDL-cholesterol, also called “good” cholesterol, is
capable of decreasing the cholesterol concentration in blood.
A high level of cholesterol can be caused by a bad diet,
excessive alcohol, smoking, overweight and lack of exercise. Diabetes may also cause increased cholesterol levels.
HealthcheX CHO– How does it work?
Once the blood sample has been added to the test well it
flows through a membrane that separates the red cells from
the plasma. The cholesterol present in the plasma reacts with
chemicals coating the membrane resulting in a blue/purple line
moving up the scale The migration distance of the coloured line
is proportional to the concentration of cholesterol present in the
sample. On completion of the test, the highest level that the
blue/purple colour reaches on the scale is read off and this
value is converted to the amount of cholesterol in the sample
using the chart contained in the kit.

HealthcheX-CHO - Test Procedure
Important issues: Before you perform the test:
- Please read the instructions for use thoroughly (this leaflet).
- Make sure you have a clock or timer ready
- The reading area on the test must be white before use. If
there is any visible sign of discolouring, do not use the
device.
- The lancet can only be used once. Do not use the lancet
until you are ready to you perform the test.
- Do not perform the test within a 4 hour period of taking
500 mg or more Vitamin C or a standard dose of
Acetaminophen (e.g. Tylenol), or Naproxen. This may
result in a lower than expected reading.
- Make sure that everything is at room temperature
- Before drawing the blood sample with a finger prick,
wash your hands with soap and water. Rinse them well
and dry them thoroughly
- Sit down and try to relax for about 5 minutes
- To increase the blood flow, rub your hands
together and let your arm hang at your side for 30
seconds.
- If you are right handed, take the blood from your
left hand. If you are left handed, from the right
hand.
- Never use a lancet used by someone else.
- Never re-use a lancet
- Use your middle finger, or a finger that does not
feel cold and is callus free.
STEP 1:
This is a very important step; read this section on how to
draw a blood sample carefully. If after reading this
information, you still have questions, please contact the
store where you bought the test or call the helpline
number listed at the end of this leaflet
- Open the pouch labelled HealthcheX CHO
cholesterol test.
- Take out the test device and place on a flat horizontal
surface
DO NOT PULL THE TAB UNTIL STEP 4!
STEP 2 :Drawing the blood sample.
Take the lancet, twist the coloured cap
and pull it off
- Place your hand, from which you are going to take the
blood, flat on the table, palm uppermost.
- Place the lancet with the opening on the side of
your finger rather than the tip. Push the lancet down,
at first it will travel easily, then you will feel some
resistance. Continue to push until you hear a “click” and then you will feel the lancet pierce the skin. After
the “click” you can remove the lancet off your finger.
- Wipe away the first drop of blood with a clean paper
tissue.
- Position your finger such that the blood drop is directly over the blood well.
STEP 3:
Adding blood sample to test device
- You must add enough blood within 3 minutes of
piercing your finger, so the black fill circle is
covered.
- Point your finger down over the blood well as
shown above. Gently massage your finger from the
base to the puncture several times. Squeeze and
release your finger tip a few times to form a
hanging blood drop. Let the drop of blood touch the
bottom of blood well on the test device.
- Add more blood as quickly as possible until the
black fill circle is covered.
Too little Too little Correct
- You can never add too much blood.
- CAUTION: Start your clock or timing device only
when the black circle in the test well is covered.
- ONCE YOU HAVE FILLED THE SAMPLE-WELL WITH
BLOOD,
WAIT
- Wait at least 3 minutes but not more than 4 minutes
STEP 4:
(a) Activating the Test
- After waiting 3 minutes but not more than 4 minutes hold the device firmly in your hand. Pull the clear plastic
tab on the right side of the device HARD until you see the
entire arrow.
- Tap the device a couple of times on the surface of the
table and lay it flat on the table.
- The OK indicator turns blue/purple in approximately 5
minutes from the start of the test.
- The end indicator turns green in about 10 – 12 minutes,
- Read the test result after both indicators change colour.
- If one of the indicators did not change colour, the test
has not been performed correctly. Repeat the test with
a new device. Once activated you cannot reuse a
device.
STEP 4 (b) Reading the result.
- Read the result within 30 minutes after the OK indicator
changed colour.
- Read the result under bright light. Find the very tip of the
blue/purple colour bar in the measurement scale, even if
fuzzy or faint.
- Use the result chart “HealthcheX CHO Test Result
Chart” to find your level of cholesterol.
- Match the number of the column labelled “Test device
reading” with the number in the column labelled“Cholesterol mmol/l”. This is your Cholesterol level.
IMPORTANT: The result chart that came within the test kit is
specific for this lot of cholesterol tests. Use only the result
chart provided with this kit. A result chart from any other kit
may give an inaccurate result.
Understanding Your Cholesterol Test Result
PLEASE NOTE: A single test result should only be
considered “indicative” of your cholesterol level and cannot
normally be considered “diagnostic”. The result must form
part of a full biochemical and clinical analysis. Bearing this in
mind, if your cholesterol test result is borderline high,
and you have other risk factors e.g. smoking, over
weight, no exercise etc., we advise you to contact your
GP or do another test after 3 to 8 weeks.

If your result is high, please contact your GP
immediately.
A high level of cholesterol is one of the most important risk
factors for coronary heart disease. (A risk factor is something
that increases your chances of getting the disease.)
The other major risk factors are:
- Diabetes
- Smoking
- High blood pressure, or have already had a heart attack, or
angina
- Physically inactive
- Not getting enough omega-3 fats
- Not eating enough fruit and vegetables
- Being overweight or obese (very overweight)
- Drinking too much alcohol
- Having too much salt.
There is also a greater risk of heart attacks among people who
have familial hyperlipidaemia – an inherited condition in which
the blood cholesterol level is very high.
Questions and Answers.
What can I do to make drawing the blood easier?
- Wash hands with warm water.
- Warm hands by rubbing them together.
- Let the arm of your selected finger hang at you side for
at least 30 seconds.
- Choose a finger that is callus-free.
- Lay selected hand, palm up, against the table.
- Press the finger stick device firmly against the side tip of
your finger. Do not pull away when triggering the finger
stick device.
- If you like, someone else can help you prick your finger.
Can both indicators change colour without giving me a
correct reading?
Yes, but an inaccurate result will occur if:
- the blood well is not filled with enough blood to cover the
black fill circle completely
- more than three minutes have elapsed in filling the blood well,
- you did not wait a full three minutes but not more than4 minutes before pulling the plastic tab
- you did not pull the plastic tab out far enough to see the
entire arrow
- you performed the test in direct sunlight.
How accurate is the HealthcheX CHO test?
The HealthcheX CHO test is as accurate as tests used by
doctors and medical labs. The HealthcheX CHO test was
evaluated in professional studies throughout the U.S. When the
instructions were followed carefully and all the steps were
performed correctly, the accuracy, on average, was 97%.
Do I need to fast before I take the test or perform it at a
specific time of day?
No. You can test yourself at any time, so fasting is not
necessary. If you repeat the test, try to do so under the same
conditions.
Will common foods, alcohol or medication affect my test results?
Generally not. Most substances will not interfere with the
test. However, you should not perform the test within a four hour
period if you have taken 500 mg or more of Vitamin C
or a standard dose of acetaminophen (e.g., Tylenol) or
Naproxen. This could cause a falsely low result.
