Stress Myocardial Perfusion Scan
A myocardial perfusion scan is a type of nuclear medicine imaging test. This means that a tiny amount of a radioactive substance, called a radioactive tracer is injected during the scan to help show the heart tissue. 
A sigmoidoscopy is a diagnostic test to check the lower part of your colon or large intestine (the sigmoid colon). This part of your colon is close to your rectum and anus.
Sympathetic Nerve Blocks for Pain
This therapy targets the sympathetic nervous system, a series of nerves that spread out from your spine to your body to help control several body functions, including blood flow.
Skull Base Surgery
Skull base surgery may be done to remove both benign and cancerous growths, and abnormalities on the underside of the brain, the skull base, or the top few vertebrae of the spinal column.
During a sympathectomy, a surgeon cuts or clamps a deep nerve that runs up and down along the spine. This prevents nerve signals from passing through it. It is used to treat heavy sweating and certain other conditions.
Sinus X-ray
A sinus X-ray is an imaging test that uses X-rays to look at your sinuses. The sinuses are air-filled pockets (cavities) near your nasal passage.
Sleep Study
The stages of sleep range from light to deep. Each stage has characteristics that can be measured. A sleep study is a number of tests done at the same time during sleep. The tests measure specific sleep characteristics and help to diagnose sleep disorders. A sleep study may also be called polysomnogram.
Strep Screen (Rapid)
This test looks for bacteria that cause strep throat and scarlet fever. Both of these illnesses are quite contagious.
Salicylate (Blood)
This test looks for high levels of salicylate, the main ingredient in aspirin. It may be used to diagnose an aspirin overdose or to monitor people taking high doses for arthritis.
Salmonella Culture (Stool)
This test looks for salmonella bacteria in your stool. Having these bacteria in your stool means you have a salmonella infection.
