FDA warns Congress about Covid test that may give false results
The Office of the Attending Physician, Dr. Brian Monahan, is responding to a public FDA warning issued yesterday that the coronavirus test administered on the Hill can be subject to false results, according to a memo obtained by NBC News.
In the memo, Monahan writes, “The Office of Attending Physician is presently monitoring a notice released this evening by the FDA regarding the performance characteristics of the Curative test to detect coronavirus using the RT-PCR system. This test system in presently used in the CVC test center at the Capitol. This test uses a tip-of-the-nose swab obtained by our patients under medical supervision.”
Monahan asserts the test "is the most accurate available" and inaccurate results plague all Covid-19 testing.
He adds they expect more information in the coming days from the FDA. The memo was fiorst reported by Politico.
Testing at the Capitol was made available in November to all members, staff and reporters working on the Hill after months of pushback to the idea from House and Senate leadership.
There is a heavy reliance on this testing system by the thousands who work in the building on a daily basis. The full House and Senate return from all across the country as they prepare to certify the Electoral College results Wednesday.

Beloved Oklahoma physical therapist dies from Covid: 'All she wanted to do was help people'
On their first date 25 years ago, Chris Kalinski realized that Rose Giroux, the woman he would eventually marry and have two sons with, knew just about everybody in Norman, Oklahoma.
They met at the physical therapy office where Rose had just started working and Chris, a college student, had been receiving treatment from a different therapist.
On that first date, they went to the store to buy ingredients to cook a romantic dinner together. Once inside, they split up, each tackling half of the grocery list.
"I walk into the freezer section and I see her talking to somebody — and it was my dad," Chris said. "I walked up and I go, 'I didn't know you knew each other, did you meet my dad like randomly or what?,'
"She said, 'Oh no, he's one of my patients.'"
Rose had a reputation around Norman of being the caretaker for just about everybody. So, when she died of Covid-19 on Nov. 23 — just six days shy of what should have been her 49th birthday — it came as a great comfort, but little surprise, to her husband to receive letters from strangers and hear stories from those whose lives she had touched.

Italy extends travel restrictions another week
ROME — The Italian government has extended travel restrictions and other measures for another week in its modified Christmas season lockdown to try to head off a new surge in coronavirus infections.
A decree approved by the Cabinet early Tuesday extends the measures to Jan. 15. At the same time, the government agreed to begin letting high school students return to class starting next week, but only in limited numbers. High schools have been on remote learning since the end of October, though elementary and middle schoolers have been attending in-person school since the start of the academic year.
Italy, the first country in the west to be slammed by the virus, has been trying to control its latest wave of infections with localized restrictions. After two months of restrictions, infections have plateaued but hospitals are still under pressure, hundreds of people are still dying every day and officials fear cases could surge again due to holiday get-togethers.
Italy has reported over 75,600 confirmed virus deaths in the pandemic, but experts say many COVID-19 deaths were not counted early in the pandemic.
