Understanding Blood Tests: What Your Results Mean
Rows of acronyms and red flags can feel alarming. Here's how to read your labs calmly — and when to act.
Ranges are guides, not verdicts
Reference ranges cover 95 percent of healthy people — so one slightly high or low value often means nothing on its own. What matters is the trend across visits, your symptoms, and how values relate to each other. Never diagnose yourself from a single red flag.
The big four we watch
Cholesterol (LDL, HDL and triglycerides) sketches your heart risk. Fasting glucose and A1C reveal blood sugar control. Thyroid hormones (TSH, T4) explain mysterious fatigue or weight shifts. And a complete blood count flags anemia, infection or inflammation early.
What happens at Fernbrook
Labs are drawn on site during your visit, results arrive within 48 hours, and your doctor explains every abnormal value in plain language — with a clear plan, not a printout and a shrug.
The takeaway
Bring your last two years of results to your next physical. Trends tell the story — and we'll read it with you.
