A DROP
OF FINGERSTICK BLOOD
AND 10 MINUTES
IS ALL YOU NEED.

Lance Finger

Use standard precautionsfor collecting and handling a fingerstick blood sample.

Locate the lancet.

Twist and pull to remove the Protective Lancet Tab.

Firmly press the lancet against the finger to puncture the skin. The lancet will retract.

Wipe away the first drop of blood with gauze.

Collect Blood Sample

Gently massage the finger to encourage blood flow to obtain a drop of blood that hangs from the finger.

Place Blood Collection Tube at a 45 degree angle below the finger, making contact with the hanging drop of blood. Avoid direct contact with the patient’s finger.

ENSURE BLOOD COLLECTION TUBE IS COMPLETELY FULL.

If the Blood Collection Tube is not full, gently squeeze the finger and add more blood.

Deliver Blood Sample

Once the Blood Collection Tube is completely filled with blood, rotate it over the Blood Transfer Zone.

ENSURE THAT BLOOD IS TRANSFERRED TO THE TEST STRIP.

Wait for ~5-10 seconds before proceeding to step #4.

If the blood does not immediately transfer onto the test strip, reverse the Blood Collection Tube’s rotation back to its original position.There will be some resistance.

Add additional fingerstick blood to the Blood Collection Tube to fill the tube, rotate Blood Collection Tube back onto the test strip.

Deliver Buffer Solution

Blood must be visible on the test strip before releasing buffer.Activate the test by firmly and fully pressing the Buffer Release Button to deliver the buffer.

If the blood does not move through the Result Window, press the Buffer Release Button again.

Place on a flat surface. Read results at 10-minutes. If the blood has not cleared at 10 minutes, wait for the background to clear before reading the test results. Do not read the test results after 1 hour.

Check Blood Transfer

Confirm the Blood Transfer Confirmation Window changed from white to pink/red to indicate the correct transfer of the blood sample.

If the Blood Transfer Confirmation Window does not change to pink/red color then the test must be discarded and patient retested with a new FebriDx® test.

Read results at 10 minutes. If the blood has not cleared at 10 minutes, wait for the background to clear before reading the test results.
Do not read the test results after 1 hour.

A blue control line must appear in the result window for the test to be valid.

bacterial infection
viral infection
negative result

Important Notes

Even if result line is faint in colour, incomplete over the width of the result window, or uneven in colour, it should be interpreted as positive.
If there is no blue control line, the test is invalid.
invalid results

Training Aids

What is the storage requirement of FebriDx®?
FebriDx® tests can be stored at room temperature (4-25°C or 39-77°F).
What patients should be tested with FebriDx®?

Patient with symptoms of a new ARI including: runny nose, nasal congestion, earache, sore throat, new cough, hoarse voice, shortness of breath in the last 7 days

Patient that is 1 year or older

Can FebriDx® be used on children?
Patients 1 year and older can be tested with FebriDx®.
What patient samples can be used on FebriDx® test?
Only fresh fingerstick blood can be used with the FebriDx® test. Venous whole blood cannot be used as MxA is an intracellular protein and once it is removed from the body, it loses stability.
When can the FebriDx® test results be interpreted?
FebriDx® test results can be read when 10 minutes have elapsed and the background is clear of blood. FebriDx® test results are stable for up to one hour. Do not attempt to interpret results beyond one hour of test initiation.
The result line is faint. Does this affect the interpretation of results?
Even if the result line is faint in colour, incomplete over the width of the test strip, or uneven in colour, it should be interpreted as positive. A positive result indicates the presence of elevated MxA and/or CRP proteins.
The result line(s) is visible but the control line is absent. Can I still report the results?
A blue control line must appear in the result window for the test to be valid. The absence of the blue control line indicates an invalid result and the patient must be retested with a new FebriDx® test.
Why do I sometimes see a CRP and an MxA line for some viral infections?
CRP is elevated in many viral infections including adenovirus and influenza. This is why CRP alone cannot differentiate between viral and bacterial infections. With FebriDx®, if the red line (MxA) is present then the result is a viral infection irrespective of CRP.
