How a thyroid workup usually unfolds
Read moreClose
Thyroid panels are one of the tests Naperville patients ask about most. MedlinePlus explains that the thyroid makes hormones that affect breathing, heart rate, weight, digestion and mood. Testing usually goes step by step:
Thyroid blood tests, based on MedlinePlus
Test
What it measures
When it is used
TSH
The pituitary hormone that tells the thyroid how much to make
Usually first; high often means underactive, low often means overactive
T4 and T3
The thyroid hormones themselves
Often added when TSH is abnormal
Thyroid antibodies
Antibodies linked to autoimmune thyroid disease
Can help identify Hashimoto's disease or Graves' disease
MedlinePlus notes that Hashimoto's is the most common cause of an underactive thyroid and Graves' disease the most common cause of an overactive one. It also says TSH can be affected by pregnancy, age over 80 and some serious non-thyroid illnesses. Tell us about every medicine and supplement you take. More on thyroid panel testing.

Self-pay patients pay from $125 for a general visit, with each lab test priced separately and explained before ordering.

Is there a closer place than Westmont, IL for lab work from Naperville, IL?

What happens if my TSH comes back abnormal?
A clinician explains what the number likely means and what comes next. MedlinePlus says an abnormal TSH usually leads to more tests, such as T4, T3 or thyroid antibodies, to find the cause. Rarely, it points to a pituitary problem. Follow-up may also involve your regular doctor.
Can I combine lab work and an X-ray in one visit?
Yes, at the main clinic, 29 N Cass Ave in Westmont, IL. It is our only clinic with X-ray, and it also collects blood and urine samples. If you might need both, go there rather than the Jewel-Osco clinic. A clinician decides which tests and images make sense after examining you.
Does living in the Will County part of Naperville, IL change anything?
No. We see patients from DuPage and Will counties alike. What matters is your insurance plan or whether you are paying self-pay. Check our list of accepted plans, call to confirm coverage, and bring your insurance card and a photo ID.
How can I help my child get through a blood draw?
Be honest and calm: tell your child it will feel like a quick pinch. MedlinePlus says a blood draw may cause a brief sting and sometimes a small bruise that fades quickly. Bring a favorite toy or tablet for distraction, and tell us if your child has fainted during a blood test before so we can plan for it.
