A lipid panel measures LDL, HDL, total cholesterol and triglycerides. MedlinePlus gives this general schedule for adults:
Ages 20 to 65: about every 5 years
Men 45 to 65 and women 55 to 65: every 1 to 2 years
Older than 65: every year
More often with higher risk, such as diabetes, high blood pressure, smoking or a family history of heart disease
A cholesterol test may require about 9 to 12 hours without food. Fast only if we tell you to, and plain water is fine.

Tired on the BNSF every morning? It could be sleep, stress or a dozen other things, and sometimes it is the thyroid. MedlinePlus explains that the thyroid makes hormones that affect breathing, heart rate, weight, digestion and mood.
Possible underactive thyroid
Fatigue and weight gain
Feeling cold when others are not
Dry skin, thinning hair, constipation
Symptoms that creep up over months
Possible overactive thyroid
Weight loss despite eating normally
Racing or irregular heartbeat
Shaky hands, nervousness, trouble sleeping
Sweating or feeling too hot
A TSH test is usually the first check. A high TSH often points to an underactive thyroid and a low TSH to an overactive one, and abnormal results usually lead to T4, T3 or antibody tests. Read more on thyroid panel testing.

Yes. Immediate Care Center of Westmont Inside Jewel-Osco, at 4 E Ogden Ave, collects lab samples on site, and it is the first clinic you reach driving east from Downers Grove, IL. Walk in or call (630) 541-6113. If you need one specific test, call first to confirm it is offered there.
Is a thyroid test part of a regular blood panel?
Not always. Many routine panels check blood counts, sugar and kidney markers but leave out the thyroid. A clinician adds a TSH test when your symptoms or history call for it. MedlinePlus notes that TSH is usually the first thyroid test ordered, with T4, T3 or antibody tests if the result is abnormal.
How long do I need to fast for a cholesterol test?
MedlinePlus says a lipid panel may need about 9 to 12 hours without food or drink other than water, which is why many people test in the morning. Fast only if we tell you to. Call (630) 324-6825 before your visit if you are unsure whether your test needs it.

Yes. We test children and adults. A urinalysis can look for signs of infection, blood, protein or sugar in the urine, and a clinician explains how to collect a clean sample. A parent or guardian should come with anyone under 18. Read about burning when you pee and UTI testing for more.
