Every year at your wellness visit, a small vial or two of blood gets drawn, sent to a lab, and a few days later you receive a results portal notification with rows of numbers and acronyms. Most people skim it, see “normal,” and move on. But those numbers are doing real work: they’re a quiet early-warning system, and understanding them is one of the best reasons to keep an ongoing relationship with a primary care provider here in Anchorage.
The Complete Blood Count (CBC)
The CBC measures the cells circulating in your blood: red cells, white cells, and platelets. Red cell numbers and hemoglobin tell us whether your blood is carrying oxygen efficiently. Low values can point to iron deficiency, blood loss, or a nutritional gap; high values can suggest dehydration or, less commonly, an issue with how your body makes blood.
White cells are your immune system’s workforce. A modest bump can mean you’re fighting off a virus you didn’t know you had. A persistent shift, up or down, is worth a closer look. Platelets, the cells that help you clot, round out the picture and occasionally flag bleeding risks before you’d ever notice a symptom.
The Metabolic Panel
The basic or comprehensive metabolic panel is a snapshot of how your kidneys, liver, and electrolytes are doing. Sodium, potassium, and chloride keep your nerves and muscles working correctly. Creatinine and BUN reflect kidney function, and a small upward drift over a few years can be the first sign that blood pressure or a medication is quietly straining the kidneys.
Liver enzymes like AST and ALT can rise with alcohol use, certain medications, fatty liver disease, or viral infections. Catching an elevation early often means a reversible cause is still reversible.
The Lipid Panel
Your lipid panel measures cholesterol and triglycerides. Total cholesterol on its own isn’t very informative; the breakdown matters. LDL is the cholesterol most associated with plaque buildup in arteries. HDL is the protective fraction. Triglycerides reflect both genetics and recent diet, and they tend to track with blood sugar trends.
What we really watch is the trajectory. An LDL of 130 is one conversation in a 35-year-old with no family history and another in a 55-year-old whose father had a heart attack at 60. This is where knowing a patient over time changes the recommendation.
Blood Sugar and A1C
Fasting glucose tells us your blood sugar at a single moment. Hemoglobin A1C estimates your average blood sugar over the past three months. The window between normal and diabetes—often called prediabetes—is where preventive medicine does its most valuable work. People in that range usually feel completely fine, but lifestyle changes, and occasionally medication, can keep them from progressing to type 2 diabetes for years or indefinitely.
Symptoms of diabetes typically show up only after blood sugar has been elevated for a long time. By then, some damage to nerves, eyes, and kidneys may already be underway. The annual blood draw is how we find it before then.
Thyroid, Vitamin D, and Other Add-Ons
Depending on your age, sex, symptoms, and history, your provider may add a TSH to check thyroid function, a vitamin D level, iron studies, or a PSA. Thyroid issues are common and often present as vague fatigue, weight changes, or mood shifts that patients chalk up to a busy life.
Vitamin D deserves a particular mention for anyone living in Southcentral Alaska. Between November and March, the sun in Anchorage simply isn’t strong enough at our latitude to make meaningful vitamin D in the skin, and deficiency is common across patients we see in South Anchorage, Eagle River, and the Mat-Su Valley. A simple test answers whether supplementation makes sense for you.
Why Trends Matter More Than Single Results
One lab result is a snapshot. Three or four years of lab results is a story. A fasting glucose that has crept from 88 to 95 to 101 over four annual visits is still technically in the normal-to-prediabetic range, but the direction is the point. The same is true for kidney function, cholesterol, and liver enzymes.
This is the practical case for preventive medicine in Anchorage with a primary care provider who knows you. An urgent care visit can tell you what’s happening today. A long-term relationship lets us see the slope, ask the right follow-up questions, and intervene while changes are small and reversible.
Your Next Step
If it’s been more than a year since your last wellness visit, or if you’ve never sat down with a provider to walk through what your numbers actually mean, that’s a reasonable place to start. Bring any past lab results you have access to, even from a previous clinic or another state. Patients across South Anchorage, Eagle River, Chugiak, Girdwood, Wasilla, and Palmer are welcome to schedule a wellness visit with our team, and we’ll go through your results together, in plain language, and build a plan that fits the life you’re actually living.
