Step 2: Prepare Sample
CAUTION:
•
The system is intended to test fresh whole blood (collected in
either EDTA or Heparin). Add the blood to the treatment
reagent within 24 hours of collection. Blood older than 24
hours may produce false negative results.
•
Use only fresh, unrefrigerated, whole blood with the LeadCare
Treatment Reagent. Blood must be stored at 10° - 32°C
(50° - 90°F) prior to mixing with treatment reagent.
•
Make sure the whole blood sample is free of clots, which can
cause inaccurate results.
1. Remove the treatment reagent cap from the tube and place it
top down on a clean surface. Do NOT allow the inside of the
cap to touch anything. This could contaminate the sample.
2. Place the full capillary tube in the treatment reagent. Insert a
plunger into the top of the capillary tube and push down,
ensuring to dispense the entire volume into the treatment
reagent.
3. Replace the tube cap. Invert the tube 8 to 10 times to mix the
sample completely.
4. The test sample is ready when the mixture turns brown. Repeat
sample collection and preparation for each sample to be tested.
CAUTION: Any visual impairment, such as color
blindness may affect the operator's ability to detect the
sample color change. Operators with vision deficiencies
should invert the tube 8 to 10 times to ensure that the sample
is properly mixed .
Storing Samples
You do not need to test the prepared sample immediately. The
mixture of blood and treatment reagent is stable for up to 48
hours at room temperature and up to 7 days refrigerated. If
refrigerated, bring to room temperature prior to analysis.
