HelpTest Code GLUCCHK Glucose Meter Check
Useful For
This test is used to compare glucose meter results with a venipuncture glucose performed by the laboratory. It will aid in monitoring meter performance and patient capillary puncture technique.
Synonyms/Keywords
Glucometer Check
Specimen Requirements
| Fasting Required | Specimen Type | Preferred Container/Tube | Acceptable Container/Tube | Specimen Volume | Specimen Minimum Volume (allows for 1 repeat) |
Pediatric Minimum Volume (no repeat) |
|---|---|---|---|---|---|---|
| No | Plasma | Lithium-heparin Plasma Separator (PST) | Lithium or Sodium-heparin Green Top (GTT) | 1 mL | 0.3 mL |
Collection/Processing Instructions
Phlebotomy:
Fill out Glucose Meter Check form with patient demographics (form is in Document Control).
Allow patient to perform capillary puncture and proceed to glucose testing on his/her meter
Log result on form where it states, "Capillary glucose meter result ______"
Draw whole blood in a GTT (green top tube) or a PST (plasma separator tube) via venipuncture
Perform glucose testing on patients meter with a portion of the unspun venous specimen
Log result on form where it states, "Venous glucose meter results ______"
Record meter type and phlebotomist initials
Send remaining blood and completed blood glucose meter check form to lab for plasma testing
Processing:
Receive GTT or PST patient sample and Glucose Meter Check form as it arrives in the lab
Verify patient identification (label or written) has been placed on the tube and the top of the form
Arrive sample
Hand-carry sample and paperwork to laboratory.
Specimen Stability Information
| Specimen Type | Temperature | Time |
|---|---|---|
| Plasma | Ambient | 5 days |
| Refrigerate | 7 days | |
| Frozen | 1 year |
Rejection Criteria
If no paperwork arrives with sample, test needs to be cancelled and credited.
Interpretations
If (the following glucose results pattern is present): Then (the following auto-comment is added):
Both meter glucose results are within 10% of the lab glucose value, this suggests the patients collection and analytical technique are acceptable, and that the meter is performing accurately. "Patients glucose meter technique appears adequate."
Both meter glucose values exceed 10% bias versus the lab glucose value; this suggests that the meter is inaccurate. ">10% discrepancy between lab venous and glucose meter results."
The meters capillary glucose bias is ≤10.0%, but the meters venous glucose bias is >10% versus the lab, then the results cannot be interpreted, as the meter may not be accurate. "Unable to interpret patient glucose meter technique from these results."
The meters venous glucose bias is ≤10.0%, but the meters capillary glucose bias is >10.0 versus the lab, then the meter appears accurate but the patients technique is in question "Patients glucose meter technique may be inadequate."
