Lab checks that matter for Oak Brook, IL's older residents
The U.S. Census Bureau counted 8,163 people in Oak Brook, IL in 2020, and about a third are 65 or older. For many, lab work is less about a new symptom and more about keeping tabs on blood pressure, kidneys, blood sugar and cholesterol.

Things that can skew a result, and how to avoid them

MedlinePlus lists several everyday things that can change lab numbers. A little care before the draw helps keep your results accurate:
Food and drink: follow fasting instructions exactly when you are given them; plain water is fine
Medicines and supplements: keep taking them unless a clinician says otherwise, but list every one, including vitamins
Hard exercise: skip a strenuous workout or round of tennis right before some tests
Not following prep: if you ate or exercised when you were told not to, say so; the test may need another day
Taking a blood thinner? Let us know before the draw, and press on the spot a little longer afterward. A small bruise can happen and usually fades on its own.

Burning, urgency, needing to go more often, or new leaks are common reasons older adults come in, and a family member often notices first. A urinalysis checks color, clarity and pH and looks for blood, protein, glucose and germs. MedlinePlus says it is often used to check for a urinary tract infection, kidney problems or diabetes.
We collect the sample on site using the clean-catch method, and a clinician explains the result along with your symptoms. Learn more about UTI testing.

How often should someone over 65 in Oak Brook, IL have cholesterol checked?
MedlinePlus advises a cholesterol test every year for adults older than 65, and sometimes more often with risk factors such as diabetes, high blood pressure or a family history of heart disease. Ask your regular doctor what fits you. We can draw the test and explain the result, and we will tell you if fasting is needed.
Does Medicare cover blood sugar screening?
Medicare.gov says Part B covers diabetes screening tests, including A1C and glucose tests, when your provider determines you are at risk. Being 65 or older counts as one factor, and a second, such as a family history of diabetes or being overweight, can qualify you. Call (630) 324-6825 to check your plan.
Can I stop by for blood work during the workday from an Oak Brook, IL office?
Yes. Both of our Westmont, IL clinics accept walk-ins from 9 AM to 6 PM on weekdays and collect samples on site. Coming down Route 83 and west on Ogden, the Jewel-Osco clinic is first. Online booking at either clinic lets you plan around meetings.
Should I skip my morning medicines before a fasting blood test?
Usually not. Keep taking your medicines unless a clinician tells you otherwise. MedlinePlus explains that some medicines and supplements can affect results, which is why we ask for a complete list. If you take a medicine that must be taken with food, call us before your visit to plan.
