Patient Call Drivers

How often should adults get routine blood work done?

For most healthy adults, routine blood work is recommended once a year as part of an annual preventive physical. However, adults managing chronic conditions such as diabetes, high blood pressure, or thyroid disorders may require blood tests every 3 to 6 months to monitor treatment effectiveness.

Do I need an appointment for blood work at DocDx?

While walk-ins are accommodated based on daily clinic capacity, scheduling an appointment in advance guarantees prompt service, reduces wait times, and ensures any fasting requirements are clearly communicated before your visit.

Does insurance cover routine blood testing?

Most major health insurance plans cover routine preventive blood work when ordered as part of an annual checkup. Specific coverage depends on your plan benefits, deductible status, and whether tests are ordered for diagnostic versus screening purposes. We recommend verifying coverage with your insurance carrier.

What is the difference between a CBC and a CMP blood test?

 A Complete Blood Count (CBC) examines cellular components of your blood, such as red blood cells, white blood cells, and platelets, to check for anemia or infection. A Comprehensive Metabolic Panel (CMP) evaluates blood chemistry, including glucose, kidney function (BUN/Creatinine), liver enzymes, and electrolyte balance.

What should I do if my blood work results show abnormal levels?

 An abnormal lab result does not automatically signify a serious medical issue—temporary factors like dehydration, recent diet, stress, or mild illness can affect blood levels. Your DocDx provider will review abnormal findings in clinical context, explain what the numbers mean, and recommend follow-up testing or lifestyle adjustments as needed.
