1.Recognize the hemoglobinometer and understand how it is used.
- Turn ON the hemoglobinometer.
Wait until you see the number code in the display (for example 950) that corresponds to
the
test card number (found on the bottle).
Wait until the flashing “test card” symbol is visible to insert the white test card into the
hemoglobinometer. You will feel it “click” into place.
Wait until you see the “blood drop” symbol to add a small drop sterilized sheep’s blood in
the
center of the test card. Be careful not to overload the well.
Wait until the reading is stable. This may take a minute. Read and record the value in the
machine’s display
Remove the white test card by lifting up slightly and pulling it out

to determine whether given readings are normal or abnormal.
