If you’re unsure whether a result needs follow-up, NurseExplain can help you understand your labs in context.

Many results that are slightly out of range are common and temporary.

WBC (White Blood Cell Count)

Slightly high or low WBC levels are common and often related to stress, minor infections, or recent illness. Mild changes are usually temporary.

eGFR (Kidney Function)

eGFR can fluctuate due to hydration, muscle mass, or medications. One slightly low value does not automatically mean kidney disease.

Sodium

Small changes in sodium levels often relate to hydration, diet, or medications. Mild shifts are very common.

Potassium

Potassium levels may vary with diet, dehydration, or certain medications. Slight changes are usually monitored.

Glucose

Glucose can be affected by food, stress, poor sleep, or illness. One elevated value does not mean diabetes

TSH (Thyroid)

Mild TSH changes are often monitored before treatment. Stress and illness can affect results.

HbA1c (Average Blood Sugar)

HbA1c reflects average blood sugar over the past 2–3 months. Borderline or mildly elevated values do not automatically mean diabetes and are often monitored over time.

Cholesterol

Cholesterol levels can fluctuate based on diet, hormones, stress, and recent illness. One elevated result is usually interpreted in the context of overall risk and trends over time.

AST / ALT (Liver Enzymes)

AST and ALT can rise temporarily due to medications, supplements, alcohol, or exercise. Mild elevations are common and often resolve without treatment.
