Diagnostics

In-house lab. Same-day answers.

Waiting days for lab results delays diagnosis, delays treatment, and delays your peace of mind. Our on-site laboratory processes most tests the same day — so your physician reviews results before you leave the clinic.

From routine blood panels to cardiac screening and hormone testing, everything happens under one roof. No separate lab visits, no phone tag chasing results, no uncertainty.

Tests We Offer

Common lab tests, explained

Start with the common panels patients ask about most often. Your physician will confirm which tests make sense for your symptoms, medication plan, and preventive care goals.

Complete Blood Count (CBC)

Measures red blood cells, white blood cells, hemoglobin, and platelets to screen for anemia, infection, inflammation, and blood disorders.

Comprehensive Metabolic Panel (CMP)

Checks glucose, electrolytes, liver enzymes, kidney function, calcium, and protein levels to give a broad snapshot of metabolic health.

Lipid Panel

Measures total cholesterol, LDL, HDL, and triglycerides to assess cardiovascular risk and guide prevention or medication decisions.

Thyroid Function Tests

Evaluates TSH, T3, and T4 patterns to help diagnose hypothyroidism, hyperthyroidism, thyroid nodules, or medication dose issues.

Hemoglobin A1c

Shows your average blood sugar over the past two to three months and helps screen for diabetes, prediabetes, and treatment control.

Vitamin D (25-OH)

Checks vitamin D levels that affect bone health, muscle symptoms, immune function, and supplementation planning.

Vitamin B12 & Folate

Screens for nutritional deficiencies that can contribute to fatigue, nerve symptoms, memory changes, and certain types of anemia.

Urinalysis

Rapid urine testing can identify signs of UTI, dehydration, kidney strain, protein, blood, glucose, and other metabolic signals.

Iron Studies

Looks at iron, ferritin, and related markers to evaluate iron deficiency, iron overload, and anemia patterns.

PSA Screening

A prostate-specific antigen blood test used for eligible patients as part of age, symptom, and risk-based prostate screening.

CRP & ESR

Inflammation markers that help evaluate infection, autoimmune activity, chronic inflammation, and response to treatment.

Additional Lab Work

Your physician may order additional tests based on symptoms, medications, preventive goals, or chronic condition monitoring.
