Abbott’s Fast COVID Test Poses Safety Issues, Lab Workers Say

Lab personnel say worries are mounting over the protection of a speedy coronavirus check by Abbott Laboratories that President Donald Trump has repeatedly lauded ― significantly, the chance of an infection to these dealing with it.

Trump and federal well being officers have promoted the benefit with which the Abbott check might be given to sufferers, whether or not at a drive-thru website or a health care provider’s workplace. Another promoting level: The check might “save personal protective equipment (PPE),” in keeping with the Department of Health and Human Services.

Yet medical employees say that there’s a critical hazard within the check’s design, one that might require far more safety — not much less ― for many who administer it.

Running a check includes swabbing a doubtlessly contaminated particular person’s nasal passage and swirling the specimen in an open container with liquid chemical substances, elevating the potential of releasing the extremely contagious virus into the air.

When HHS announced it had purchased tens of hundreds of Abbott’s point-of-care checks for public labs and others throughout the nation, it famous that “only gloves and a facemask are necessary” to manage it.

The notion of donning much less safety runs opposite to suggestions from the Centers for Disease Control and Prevention, and medical employees worry that they could possibly be contaminated whereas testing others.

Abbott says the check can return a constructive end in as little as 5 minutes. And its improvement was welcome information for governors and hospitals throughout the nation desperately looking for COVID checks for sufferers and scarce protecting gear for medical employees.

“What makes this test so different is where it can be used: outside the four walls of a traditional hospital such as in the physicians’ office or urgent care clinics,” says Abbott Labs on its web site. It has already been deployed in public well being labs and several other drive-thru websites, the place folks wait in parking tons usually occupied by casino- and cinema-goers.

But lab officers and medical diagnostic specialists say working the Abbott machine — used for years to detect different pathogens, together with the flu ― requires a technician to go away affected person specimens out within the open. Gloves and a masks alone wouldn’t shield them.

Standard precautions for biosafety safety in labs embody good hand hygiene and the usage of lab coats or robes, gloves and eye safety to guard medical employees when a specimen is being manipulated, in keeping with the CDC. Health employees gathering specimens ought to put on an N95 masks and different PPE.

To run the Abbott check, medical employees or sufferers themselves swab a person’s naval cavity to gather a specimen. Then, the swab is put again into its authentic wrapping, doubtlessly exposing employees to contaminated supplies after they deal with it, in keeping with Michael Pentella, the pinnacle of Iowa’s state public well being lab who chairs the Association of Public Health Laboratories’ biosafety and biosecurity committee.

Abbott’s directions direct employees to “vigorously mix” the swab with liquid in an open vessel within the machine for 10 seconds — a form of open system that Pentella referred to as “unusual.”

“This is the only test I know of where you take the swab and you put it back in the paper wrapping,” stated Pentella, who hasn’t used the Abbott speedy checks in his lab however has heard issues about security from colleagues. “It’s the contamination that could be associated with the wrapper that has some biosafety professionals concerned.”

The committee he chairs plans to situation security suggestions for lab employees dealing with the product.

“It’s not like you shouldn’t use the instrument,” Pentella stated. “You just have to use it safely.” While Abbott advises clients to make use of common precautions for safeguarding well being care employees, the extent to which that occurs is as much as every group, Pentella stated. “We don’t want to give this disease to anyone.”

Another longtime medical diagnostics knowledgeable expressed shock on the method the Abbott check is carried out — swab gathered from a doubtlessly contaminated affected person should be brazenly combined in liquid.

“The best point-of-care instrument is exactly like an automated pencil sharpener,” stated the knowledgeable, who like others spoke on the situation of anonymity out of worry of retaliation. “You do nothing else.”

A spokesperson for the New York City Department of Health and Mental Hygiene equally stated officers have been anxious about biosafety and contamination due to how the check is carried out, saying its open construction might contaminate the particular person performing the check in addition to the realm across the machine.

Trump has been a dependable pitchman for Abbott’s check, calling it a “whole new ballgame” as he confirmed off the machine within the Rose Garden. In public remarks from Feb. 29 to April 6 ― the day HHS introduced it had bought hundreds of checks — Trump referred to as out Abbott 14 occasions, in keeping with a evaluation of his remarks throughout every day White House briefings and associated occasions.

“Now, a lot of people love the Abbott test. So do I. You know, the Abbott test is great because it’s, boom, it’s ― they touch, they put it in, and in five minutes you have [a result],” Trump stated this week.

As one former HHS official put it: “He likes showy things that can look good.” A White House spokesperson declined to remark additional on Trump’s reward of the corporate.

Certainly the preliminary HHS buy of 30,000 Abbott checks to distribute throughout the nation was supposed to try this. About 13,500 of them went to public well being labs plus the CDC’s central lab in Atlanta, in keeping with a division spokeswoman. The Indian Health Service acquired 10,000 checks, and roughly 5,000 have been put aside for the CDC’s International Reagent Resource for states to replenish provides.

Public well being labs seemed to be in line for barely extra checks and units than indicated in an earlier HHS doc, obtained by Kaiser Health News, which confirmed state and native labs would obtain a complete 5,500 checks and the CDC lab would get 800.

On April 6, when HHS introduced its order, hundreds of thousands of Americans have been ready on COVID checks. Multiple public well being labs that acquired a batch from Abbott stated they obtained 15 units and provides to conduct 120 checks. Even calibrating the machine would deplete a portion of these — earlier than labs might run affected person samples. HHS additionally ordered 50 Abbott ID Now machines for Alaska due to its distant location, in keeping with company spokesperson Mia Heck.

When requested why HHS stated solely gloves and a face masks have been essential to administer the check, Heck stated the division deferred to CDC tips.

Certain states have supplied steerage to these dealing with affected person specimens that’s much like the CDC’s. For instance, the Washington state well being division suggested suppliers to make use of “appropriate personal protection” when gathering affected person specimens ― at minimal, a robe, gloves, N95 respirator masks and goggles or a face defend, in keeping with emails obtained by means of a public information request in King County, Washington.

Gary Procop, director of virology on the Cleveland Clinic, stated he recommends that personnel both put on applicable protecting gear or use the check in a organic security cupboard, which protects employees behind a glass defend. The giant built-in well being system is weighing whether or not to make use of the short check in sure settings, together with the place there’s a low prevalence of illness, and had issues about employees dealing with open swabs.

“What you really want to have is droplet precautions,” he stated in an interview.

As security issues develop, some state officers are nonetheless complaining a few lack of provides from Abbott — regardless of its statements that it could manufacture 50,000 checks per day.

“It’s incredibly frustrating because there was a lot of talk about this device, there was a lot of hype on it nationally, and that was wonderful,” New Hampshire Gov. Chris Sununu, a Republican, stated at a information convention this month. “And then when they showed up, expectations were set really high as they should be. But to actually have 13 of these devices and have no way to use them, I’m banging my head against the wall.”

Abbott has received appreciable publicity for the quick Abbott check since FDA granted emergency authorization on March 27. The firm has partnered with CVS Health and Walgreens to arrange drive-thru COVID testing websites in a number of states.

As of Monday, 9 of 15 deliberate Walgreens websites in seven states are open with the Abbott checks. Walgreens pharmacists are tasked with overseeing sufferers and “PPE is used throughout the process,” a spokesperson stated, with out responding to questions on protocol for dealing with specimens and which particular objects staff put on.

CVS Health is working 5 drive-thru websites in 5 states, with every capable of display screen 750 to 1,000 folks a day, spokesperson Christine Cramer stated. Nurse practitioners and doctor assistants dealing with specimens use gloves, robes, N95 masks and eye shields or goggles.

“We won’t open a site until we are sure we have what we need,” she stated.

In Washington, folks anticipated to be in shut contact with Trump ― together with reporters masking his every day coronavirus briefings — have additionally been examined on Abbott machines.

Abbott spokesperson Darcy Ross stated the corporate has shipped greater than 850,000 speedy checks since April 1, though it’s unclear what number of went to private-sector shoppers versus public well being websites.

“We recommend our customers follow the CDC recommendations and guidelines for point-of-care sample handling and PPE. Our product information directly links to CDC guidelines,” she stated.

The Abbott checks have had a number of different hiccups. For instance, the Food and Drug Administration this month stated Abbott would revise its directions after one methodology for preserving specimens ― generally known as viral transport media — brought about inaccurate outcomes as a result of affected person samples have been too diluted.

Pentella, the Iowa lab official, stated, “People are shifting their concern from the viral transport media to, now you have a swab in a wrapper that’s potentially contaminated with nasal secretions from the patient.”

On an April 15 name held by FDA officers on the event and validation of COVID-19 checks, Timothy Stenzel, director of the company’s Office of In Vitro Diagnostics and Radiological Health, was requested whether or not the company has a course of to take away authorizations already granted for checks discovered to be ineffective or harmful, in keeping with audio obtained by Kaiser Health News. The FDA has granted greater than 40 emergency approvals for COVID-19 checks since Feb. four.

He responded that the FDA’s “traditional way” is for the company and developer to make selections collectively on the most effective path ahead.

“We always first want to engage the developer to understand what the performance issues might be,” he stated, “to try to understand what the root cause is.”

“If there are indeed performance issues,” he stated, “what is the best way to address that as quickly as possible?”
