Dehydration can spike sodium levels, potentially misleading tests related to hormonal or renal issues.
Hemoconcentration can falsely elevate cholesterol levels, leading to unnecessary treatments.
Dehydration concentrates glucose, resulting in misleadingly high readings, particularly concerning for diabetics.
Well-hydrated veins are easier to access, minimizing discomfort and improving sample integrity.
