Compiled glucose/A1C interpretation: glucose 450 = hyperglycemia (normal 70-100 fasting, diabetic range >126 fasting). A1C 12% = poor diabetes control. BUT RED FLAG: temperature 40°C (104°F) is out of range for specimen validity. High temperature can falsely elevate glucose. Action: 1) Check collection temperature—should be room temp, 2) Investigate if specimen was exposed to heat, 3) Repeat draw if temperature > 37°C or specimen integrity questioned. Note: if both glucose AND A1C high independently, patient likely has real hyperglycemia, but temperature issue must be documented.

Glucose 450 mg/dL

Critical hyperglycemia — above critical high threshold

A1C 12%

Severely uncontrolled diabetes — consistent with high glucose

Temperature Flag

40°C collection temp — high temp falsely elevates glucose

Action

Investigate specimen temperature — repeat draw to confirm

Document

Log temperature issue and corrective action regardless of outcome

Compiled quality control troubleshooting: controls outside limits = instrument may not be accurate. ACTION: 1) STOP running patient samples until QC passes, 2) Repeat QC (sometimes reagent issue or calibration drift). 3) If QC still fails: recalibrate instrument using manufacturer protocol, 4) Replace control reagents (expired or degraded), 5) Run QC again, 6) If still fails: contact manufacturer support or take analyzer offline. Key: never report patient results when QC is failed—those results are unreliable. Document QC failure and corrective action for accreditation.

ToolRouter research

Step 1

STOP patient testing immediately — do not report results

Step 2

Repeat QC with fresh controls — rule out reagent issue

Step 3

Recalibrate per manufacturer protocol if repeat QC fails

Step 4

Replace control materials if expired or degraded

Step 5

Document all QC failures and corrective actions — accreditation required

Compiled hemolysis assessment: hemolyzed specimens = red blood cells broken open, release hemoglobin into serum. Problem: hemoglobin interferes with many tests (potassium falsely high, LDH falsely high, bilirubin masked). Action: reject the specimen—request redraw. Why it happened: rough handling, shaking, small needle gauge, prolonged tourniquet application, temperature. Prevention: teach phlebotomists—gentle handling, correct needle size, tourniquet <1 min, transport at correct temperature. Some tests (hemoglobin, hematocrit) not affected by hemolysis; if only those requested, can proceed. Lab policy varies—check your facility protocol.

ToolRouter research

Impact

Potassium falsely elevated · LDH falsely elevated · bilirubin masked

Action

Reject specimen — request redraw for affected tests

Cause

Rough handling, shaking, small needle, tourniquet >1 min

Exception

Hemoglobin/hematocrit testing unaffected — may proceed if only those ordered

Prevention

Train phlebotomists on gentle handling and correct technique

Compiled critical value protocol: potassium 7.2 = CRITICAL HYPERKALEMIA (critical range usually >6.0 or <2.5). High potassium = cardiac dysrhythmia risk (abnormal heart rhythm, cardiac arrest). ACTION IMMEDIATELY: 1) Double-check result (verify not instrument error), 2) Notify provider STAT by phone (not text, not email), 3) Document: provider name, time of call, what you reported, provider response, 4) Follow up—ensure patient gets treatment (calcium gluconate, insulin, etc.). Critical values must be reported immediately—don't wait. If can't reach provider, escalate to supervisor/charge nurse. Patient safety depends on speed.

Status

CRITICAL — hyperkalemia above 6.0 mEq/L threshold

Risk

Cardiac dysrhythmia and arrest risk — life-threatening

Step 1

Verify result — confirm not instrument error before calling

Step 2

Call provider STAT by phone — not text, not email

Step 3

Document: provider name, time, report given, provider response
