Living with diabetes in Willowbrook, IL: the tests that track it
Diabetes testing is one of the reasons Willowbrook residents list for visiting us. If you already have diabetes, lab work is less about diagnosis and more about keeping watch. A clinician decides what fits you, but these tests come up most:
Common monitoring tests, based on MedlinePlus
Test
What it tracks
How often it often comes up
A1C
Average blood sugar over roughly 2 to 3 months
At least twice a year with diabetes
Basic metabolic panel
Glucose, body salts and kidney markers (BUN and creatinine)
As your clinician advises
Lipid panel
LDL, HDL, total cholesterol and triglycerides
Yearly after 65, and often more with diabetes
Urinalysis
Glucose, protein, ketones and signs of infection in urine
The A1C measures how much glucose is attached to hemoglobin in your red blood cells. Because it depends on those cells, MedlinePlus lists several things that can throw it off:
Anemia or other blood disorders
Kidney failure or liver disease
Certain medicines, such as opioids and some HIV medicines
Pregnancy, which is why the A1C is not used to diagnose gestational diabetes
When one of these applies, a clinician may pair the A1C with a fasting glucose test or a complete blood count. Fast only if we tell you to.
Test results are only part of the picture. MedlinePlus explains that a provider weighs your numbers against your symptoms, your history and any other tests, and may repeat a test if a result seems off. If something does not add up, a clinician will explain why a recheck or a different test makes sense.

Out-of-state plans vary, so call to check, or pay self-pay: a general visit starts at $125, and each lab test is priced separately and explained before it is drawn.

MedlinePlus says people with diabetes usually need an A1C at least twice a year, and people with prediabetes every 1 to 2 years. Your own schedule depends on your treatment and how stable your numbers are. A clinician at our Westmont, IL clinics can draw the test and explain the result, and your regular doctor sets the long-term plan.
Why would my A1C and my home glucose readings not match?
They measure different things. Home readings capture a single moment, while the A1C reflects an average over about two to three months. MedlinePlus adds that anemia, kidney or liver disease and some medicines can make the A1C less accurate. Bring your log so a clinician can compare.

Can a urine test show problems from diabetes?
A urinalysis can find glucose, protein or ketones in the urine, and MedlinePlus notes it is often used to help check for diabetes and kidney problems. It does not replace blood tests such as the A1C or a metabolic panel. A clinician decides which tests fit your situation and explains what the results mean.
