Advanced Weekend 2-Day Health Checkup

Mention when booking: Mention a pacemaker or implanted defibrillator: the test passes a weak electric current through the body and has traditionally not been recommended with these devices.

Usually needs at least 8 hours without food or drink except water beforehand.

Mention when booking: If you take insulin or other diabetes medicine, ask the prescribing doctor how to manage it while fasting, and mention it to the center.

Guaiac-based kits usually ask you to avoid red meat, NSAIDs and more than 250mg of vitamin C for a few days beforehand; FIT kits usually need no diet change.

Mention when booking: Tell the center which kit you were given, and ask the prescribing doctor before stopping aspirin taken for the heart.

Usually needs no special preparation; several samples on different days are often requested, since parasites don't show up daily. The stool shouldn't mix with urine, toilet paper or toilet water.

Mention when booking: Ask how and when to return the samples, especially if you are collecting over several days.

Usually needs a clean-catch (midstream) sample; some tests instead ask you to collect all urine passed over 24 hours.

Mention when booking: Ask which specific urine test your provider ordered, since collection instructions vary by test.

For a transabdominal scan, drinking water beforehand to fill the bladder is common; for a transvaginal scan, an empty bladder is usual instead.

Mention when booking: Tell the center which type of scan you expect, and mention if you are, or might be, pregnant.

Usually needs a clear-liquid diet the day before and a split-dose bowel-cleansing prep taken the evening before and morning of the exam; drinking extra fluids helps avoid dehydration.

Mention when booking: Tell the center about heart, kidney or lung disease, blood thinners, diabetes medicine, aspirin, arthritis medicine or iron; ask the prescribing doctor before changing any medicine.

Afterwards: After sedation, no driving, operating machinery or signing legal documents for the rest of the day; someone should take you home.

Usually needs about 8 hours without food or drink, including water, beforehand.

Mention when booking: Tell the center about heart or lung disease, aspirin, blood thinners, arthritis medicine, insulin or iron, and ask the prescribing doctor before changing any medicine.

Afterwards: After sedation, no driving, machinery or legal documents that day; get a ride home. Contact a doctor for fever, trouble swallowing, chest or belly pain, or black stools; bleeding can start days later.

Usually asks that you avoid intercourse, douching and tampons for 24 hours beforehand, and avoid scheduling during your period if possible.

Mention when booking: Tell the center if you are having unexpected bleeding, think you might be pregnant, or have had an abnormal Pap or positive HPV test before.

Afterwards: Light bleeding or spotting afterward is common and usually stops within a few hours.

Often done with a camera that photographs the retina without drops; some centers use dilating drops that widen the pupil, which blurs vision for a few hours afterward.

Mention when booking: Mention any eye pain, halos around lights, or a narrow drainage angle or angle-closure glaucoma history.

Afterwards: If drops were used, vision may be blurry and light-sensitive for a few hours; have someone else drive. Sudden eye pain, headache, blurred vision or halos after dilation need urgent care.
