A small molecule screen is a procedure in which small molecules (typically organic compounds with a molecular weight under ∼1,000 g/mol) are systematically tested for their ability to activate, perturb, or modify a target or a biological process of interest.
How is colon cancer screening done?
The tests used to screen for colorectal cancer are described below. Colonoscopy. A colonoscopy allows the doctor to look inside the entire rectum and colon while a patient is sedated. A flexible, lighted tube called a colonoscope is inserted into the rectum and the entire colon to look for polyps or cancer.

How accurate is cologuard?
How Accurate is the Cologuard test? Cologuard can detect 92% of cancers but only 42% of large precancerous polyps. Cologuard is better at detecting cancer than FIT (92% vs 70% for FIT), but the false positive rate is higher. Cologuard has a 12% false-positive rate, and that rate increases as people age.
What is high throughput screening used for?
High-throughput screening (HTS) is a key process used in drug discovery to identify hits from compound libraries that may become leads for medicinal chemistry optimization.
What does it mean to screen compounds?
Compound Screening is defined as the identification of compounds that could be promising candidates for drug development, before it advances to the more-costly stages of preclinical and clinical trials. Compound Screening is also done to identify the potential side effects caused by administration of such compound(s).
What is the prep for cologuard?
The Cologuard test does not require any preparation. You do not need to change your diet or medicines before the test.
Does cologuard need a prescription?
