Illinois law (Hospital Uninsured Patient Discount Act, 210 ILCS 89): an uninsured Illinois resident with family income up to 600% of the federal poverty level (300% at rural and critical access hospitals) can apply for a discount that brings the bill down to about 135% of the hospital's cost; up to 200% (125% at rural hospitals) medically necessary care is free. A hospital may collect no more than 25% of family income in 12 months. Ask the billing office for the application. Other states' laws.

STD tests are lab tests, and each infection is usually its own code: chlamydia and gonorrhea are often run on the same urine sample or swab but billed as two tests. The listed price covers the lab test only; the visit, the sample collection or blood draw, and any confirmation test after a positive result are billed separately.

Paying cash: what to do

  • Check your local health department or a Title X family planning clinic, which offer free or sliding-fee STD testing in many areas.
  • Ask whether chlamydia and gonorrhea will be billed as two tests or as one combined price, and whether the visit fee is included.
  • Ask what the follow-up test costs if a screen is positive, since HIV, syphilis and hepatitis C screening results are confirmed with a second test.
