Quality Control
LeadCare II Blood Lead controls are intended to monitor the accuracy and
precision of your blood lead testing using the LeadCare II Blood Lead Testing System.
How Often to Test with Controls
Test two levels of quality control:
1
on each new lot, or on each new shipment of materials
with each new operator
monthly, as a check on continued storage condition
when problems (storage, operator, instrument, or other) are suspected
or identied
if required by your laboratory’s standard QC procedure
Results obtained on control samples that are within the expected ranges means that your LeadCare II System is operating properly. Refer to the LeadCare II User’s Guide for additional important information on quality control.
Recommendations for Clinical Laboratory Improvement Amendments of 1988 (CLIA) Waiver Applications for Manufacturers of in Vitro Diagnostic Devices, Guidance for Industry and FDA Staff:, p. 34, viewed 17 August 2017, <https://www.fda.gov/downloads/MedicalDevices/DeviceRegulationandGuidance/GuidanceDocuments/ ucm070890.pdf>.

Analyze the control sample according to the instructions provided in the Analyze
the Sample section. Repeat this process for the Level 2 control.
Lead Control Test Results: Expected Results
Control target values and acceptable ranges are provided on the control vial label. The blood lead result you obtain for a control should be within the acceptable range. If the results are not within the listed range, refer to the Troubleshooting section of the User’s Guide. If, after following the instructions, the controls are still out of range, call Product Support.
CAUTION: Do NOT proceed to patient samples unless both Level 1 and Level 2 control results are within the acceptable ranges.
Using the Controls (See Prepare the Sample for Additional Information)
Treat the controls as you would a patient blood sample. Refer to the LeadCare II User’s Guide for detailed instructions on how to perform blood lead testing.
Wipe the outside of the
capillary tube to remove any excess control.
Inspect the capillary tube
to conrm that it is properly lled (see step 5 on page 7).
Place the capillary tube
into the treatment reagent tube. Insert a plunger into
the top of the capillary tube
and push down, ensuring the entire volume of control
is dispensed into the
treatment reagent.
Replace the tube cap. Invert the tube 8 to 10 times to mix the sample completely.
Control material in treatment
reagent tube will appear red.
Label a fresh treatment
reagent tube “Level 1 Control”.
After thorough mixing, remove the cap from the Level 1 control vial and place it top down on a clean surface.
Holding the capillary tube almost horizontally with the green band on top, ll the tube to the 50 µL black line. Replace the cap on the control vial.

of Childhood Lead Exposure and Poisoning. Retreived from: http://www.pehsu.net/_Library/facts/medi­cal-mgmnt-childhood-lead-exposure-June-2013.pdf.
Interpreting Patient Test Results
The analyzer’s display window shows the blood lead result. The result is in micrograms (µg) of lead per deciliter (dL) of whole blood. No calculation is needed. Results are displayed to one decimal place. The reportable range of the test is 3.3 to 65 µg/dL.
Low” in the display window indicates a blood lead test result less than 3.3 µg/dL. When this occurs, report the blood lead result as less than (<) 3.3 µg/dL.
Interpreting Patient Test Results
High” in the display windows indicates a blood lead test result greater than 65 µg/dL. When this occurs, report the blood lead result as greater than (>) 65 µg/dL. “High” results on LeadCare II should be followed up immediately
as an emergency laboratory test.
Blood lead test results should be shared with the patient’s physician for interpretation and to determine when retesting and follow-up care are necessary.
In 2012, the Centers for Disease Control & Prevention (CDC) established 5 µg/dL as the new “reference level” for lead in blood, a change from the previously utilized “level of concern” of 10 µg/dL.2
Repeat Testing Guidelines3
If blood lead level Child’s age* Perform re-test
(capillary sample allowed) within
<5 µg/dL < 12 months 3 - 6 months
1 - 5 years 6 - 12 months
If blood lead level Child’s age* Perform diagnostic test
on venous blood within
5 - 14 µg/dL 1 - 5 years 1 - 3 months
15 - 44 µg/dL 1 - 5 years 1 - 4 weeks
>44 µg/dL 1 - 5 years 48 hours
* Ensure blood lead levels are checked at both 1 and 2 years of age.
Capillary blood samples that generate an elevated lead level should be conrmed with a venous sample. Venous samples should be sent to a reference laboratory for conrmation.
In cases where the capillary specimen demonstrates an elevated lead level but the conrmation venous sample does not, it is important to recognize that the child may live in a lead-contaminated environment that resulted in contamination of the ngertip. Efforts should be made to identify and eliminate the source of lead in these cases.
3
Consult your local public health department, or the CDC, for further information on actions to be taken for blood lead results that are greater than 5 µg/dL.
Report all blood lead test results to the appropriate state or federal agency.

Troubleshooting of Inaccurate Results
Scenario 1: Troubleshooting results below the target or expected value
• Make sure the analyzer is calibrated to the sensor lot in use.
• Make sure the sensor is inserted under the sensor guides and sits ush on the sensor deck.
• Check the expiration date on the test kit box. Do NOT use a test kit that is beyond the expiration date. Note: the analyzer will not perform a test when it is calibrated for a sensor lot that has expired.
• Use only fresh, whole blood from patients. Do NOT use plasma or serum.
• Less than 50 µL in the capillary tube will tend to produce lower blood lead results.
• Make sure that there are no clots or bubbles in the capillary tube.
• Always mix the blood sample with treatment reagent. Results generated with untreated blood are not accurate.
• Do NOT use clotted blood. If there are clots in the blood, obtain a new sample.
• Operate the analyzer only within the specied humidity range – 12 to 80% relative humidity.
• Make sure that the analyzer, test kit, and sample are all at the same temperature before testing. Note: The analyzer will not initiate a test if the temperature is changing too rapidly, or if the temperature is outside of the operating range.
• Avoid operating the LeadCare II System in drafts.
• Make sure the blood and treatment reagent are thoroughly mixed before placing onto the sensor.
• Keep the lid on the sensor container closed to protect unused sensors.
• Do NOT touch the sensor while running a test.
Scenario 2: Troubleshooting results above the target or expected value
• To avoid contamination of the skin’s surface, wash patient’s hands thoroughly with warm soapy water prior to collecting a ngerstick sample. Use clean gloves during testing and keep your gloved hands clean.
• Make sure the analyzer is calibrated to the sensor lot in use.
• Check the expiration date on the test kit box. Do NOT use a test kit that is beyond the expiration date.
• Make sure you are using lead-free collection devices.
• Do NOT touch the ends of the capillary tubes or the plungers. This could cause contamination.
• Excess blood on capillary tube. Be sure to wipe excess blood from the tube with a downward motion. The accuracy of the test depends on lling the capillary tube with 50 µL. Excess blood on the outside of the tube may produce higher blood lead results.
• Do NOT use clotted blood. If there are clots in the blood, obtain a new sample.
• Do NOT leave the treatment reagent tube uncapped other than to add the blood sample and remove the blood sample/treatment reagent mixture.
• Make sure to thoroughly mix blood with the treatment reagent. The mixture should turn brown before you place it on the sensor.
• Operate the analyzer only within the specied humidity range – 12 to 80% relative humidity.
• Make sure that the analyzer, test kit, and sample are all at the same temperature before testing.
• Do NOT use a sensor that has been dropped on the oor or exposed to contaminants.
• Do NOT touch the sensor while running a test.
