A few words about Shield- a new blood test for colorectal cancer screening
🌸 FDA approved Guardant Health's Shield™ blood test as a primary screening option for colorectal cancer.
🌸 Shield test meets performance requirements for Medicare coverage.
🌸 Intended for average risk individuals aged 45 or older; not for high-risk individuals.
🌸 Detects DNA fragments shed by tumor cells and precancerous growths.
🌸 It is not an equivalent alternative to colonoscopies, which are more accurate and can remove precancerous polyps.
🌸 Shield test recommended every 3 years, colonoscopy every 10 years.
🌸 False positive rate of Shield test is about 10%.
🌸 Clinical trial: Shield may miss 1 in 10 with precancerous lesions and 1 in 1,000 with cancerous lesions.
🌸 Current screening: fecal tests every 3-5 years, colonoscopy every 10 years.
🌸 Some patients resist fecal tests and colonoscopies due to inconvenience and preparation requirements.
🌸 Blood tests might lead to increased screening uptake due to convenience.
🌸 Positive Shield test results require follow-up colonoscopy.

Shame on @turkishairlines refusing to let my parents board, asking for a fare difference for a flight that the airline changed itself. Made 12 phone calls in 1 day and keep getting asked to submit an online complain while parents are stuck at the airport. #pathetic@TK_HelpDesk
@BartsQuandry @SawyerMerritt I have bought 2 Model S . Amazing cars , FSD is great too but I ll probably avoid another one due to massive depreciation.
