Overall Summary
Simple language, not medical jargon
A few values are mildly outside the usual range. Nothing in this preview suggests panic, but the lower hemoglobin and higher LDL are worth discussing with your doctor together.
11.8 g/dL
Lower than the listed range, which can happen for several reasons and should be interpreted with the rest of your CBC.
142 mg/dL
Flagged high on many lab reports. The meaning depends on age, heart risk, and the rest of your cholesterol panel.
