Your lab results, explained: What we test and why
Every LiveRounded subscription includes baseline lab work and ongoing monitoring panels. We include labs because we believe treating a patient without knowing their baseline numbers is guesswork — not medicine.
This article explains what each test in our standard panel measures, what abnormal results mean in the context of GLP-1 or hormone therapy, and how your NP uses those numbers to make clinical decisions.
Complete Blood Count (CBC)
The CBC measures the components of your blood: red blood cells, white blood cells, and platelets. For patients starting GLP-1 or hormone therapy, it gives us a baseline and catches underlying conditions — like anemia or infection — that might affect how you respond to treatment or what symptoms you experience.
Low red blood cell counts (anemia) can cause fatigue that's easy to misattribute to medication side effects. Knowing your baseline helps us distinguish between the two.
Comprehensive Metabolic Panel (CMP)
The CMP is a broad metabolic snapshot covering kidney function (creatinine, BUN), liver function (ALT, AST, alkaline phosphatase), blood sugar (glucose), electrolytes (sodium, potassium, calcium), and total protein and albumin.
For GLP-1 patients, liver enzymes matter: fatty liver disease is common in patients with obesity, and we want to confirm treatment isn't causing any liver stress. Kidney function matters because GLP-1s reduce caloric and fluid intake — if your kidneys are already under strain, hydration becomes even more important.
For hormone optimization patients, the CMP helps us monitor for lipid or metabolic changes that can accompany testosterone or estrogen therapy over time.
HbA1c (Hemoglobin A1c)
HbA1c measures your average blood sugar over the past 2–3 months. It's the single most important number for understanding insulin resistance and pre-diabetes risk.
For GLP-1 patients, this is especially relevant: semaglutide and tirzepatide were originally developed as type 2 diabetes medications. Many of our weight-loss patients have pre-diabetes or undiagnosed insulin resistance — and their A1c often improves significantly within the first 3–6 months of treatment. We track this to document the metabolic benefit of treatment beyond weight loss alone.
A normal A1c is below 5.7%. Pre-diabetes is 5.7–6.4%. Type 2 diabetes is diagnosed at 6.5% or above.
Fasting Lipid Panel
The lipid panel measures total cholesterol, LDL (low-density lipoprotein), HDL (high-density lipoprotein), and triglycerides. These numbers help us assess cardiovascular risk — which matters because obesity, insulin resistance, and hormonal imbalances all affect lipid metabolism.
GLP-1 therapy consistently improves lipid profiles, particularly triglycerides and LDL. We track this as evidence of treatment benefit. If your lipids worsen despite treatment, it's a clinical signal that requires investigation.
For hormone optimization patients, testosterone therapy in men can sometimes lower HDL. We watch for this and discuss cardiovascular risk management proactively.
Thyroid Stimulating Hormone (TSH)
TSH is the pituitary hormone that signals your thyroid to produce thyroid hormone. An elevated TSH indicates hypothyroidism — an underactive thyroid — which causes fatigue, weight gain, and difficulty losing weight even with caloric restriction.
We test TSH at baseline because undiagnosed hypothyroidism is one of the most common reasons patients struggle with weight loss despite consistent effort. If your TSH is elevated, we'll discuss referral for thyroid management — because treating the underlying condition always comes first.
Sex hormones (for hormone optimization patients)
For patients in our hormone optimization program, we measure testosterone (total and free), estradiol, SHBG (sex hormone binding globulin), LH, and FSH. In women, we also measure progesterone. For men on testosterone therapy, we monitor hematocrit (red blood cell percentage) because testosterone increases red blood cell production — levels that get too high increase clotting risk.
PSA (prostate-specific antigen) is checked at baseline and periodically for men on testosterone therapy. This is standard clinical practice — not something to alarm you, but something to track.
How we use your results
Lab results don't exist in isolation. Your NP reviews every result in the context of your symptoms, medications, and health goals. An LDL of 130 means something different in a 35-year-old with no family history of cardiovascular disease than in a 50-year-old with a father who had a heart attack at 55.
After each lab panel, your NP will send you a results summary with plain-language interpretation and any recommended changes to your treatment plan. If something needs to be addressed urgently, we contact you directly — we don't make you log in to a portal to find a concerning result.
