How Often Should You Get Bloodwork Done?

Bloodwork is one of the most useful tools your doctor has for understanding what is happening inside your body. But how often you actually need it depends on your age, health status, risk factors, and whether you are managing any ongoing conditions.

General Guidelines for Healthy Adults

• Ages 18 to 39 with no known conditions: basic bloodwork every 2 to 3 years at a minimum, or annually if your doctor recommends it.

• Ages 40 to 49: annual bloodwork is increasingly common. Lipid panels, blood sugar, and thyroid checks become more important.

• Ages 50 and older: annual comprehensive bloodwork is standard for most adults. More frequent monitoring if managing any chronic conditions.

If You Have a Chronic Condition

People managing ongoing health conditions typically need bloodwork more frequently. General guidelines include:

• Diabetes: A1C every 3 months if uncontrolled, every 6 months if well-managed.

• Thyroid conditions: TSH every 6 to 12 months when stable, more frequently when adjusting medication.

• High cholesterol: lipid panel every 3 to 12 months depending on treatment.

• Kidney disease: kidney function panels every 3 to 6 months.

• Heart conditions: varies widely, follow your cardiologist's schedule.

• Autoimmune conditions: depends on medication and disease activity.

Annual Panels Worth Considering

• Complete blood count (CBC)

• Comprehensive metabolic panel (CMP)

• Lipid panel

• Thyroid (TSH)

• Fasting glucose or A1C

• Vitamin D and B12

• Iron studies if indicated

The Best Rule of Thumb

Follow your doctor's recommendations. Annual physicals are a good time to review what bloodwork is appropriate for your age and health profile. If you have symptoms you are concerned about, do not wait for your next scheduled visit.

Frequently Asked Questions

Can I get bloodwork without symptoms?

Yes, and it is encouraged. Routine bloodwork can catch elevated cholesterol, blood sugar, thyroid issues, and other conditions before symptoms appear.

Does getting more bloodwork hurt anything?

No. Routine bloodwork is safe and minimally invasive. The main downside of over-testing is cost, which is worth discussing with your doctor when deciding on a schedule.

Can I schedule my own bloodwork without a doctor?

You need a lab order from a licensed provider. Your primary care doctor, or an online telehealth provider, can issue one.
