Making your med tech minutes count
Chemistry analyzers for medium-and high-volume labs
When a medium-or high-volume laboratory chooses a chemistry analyzer, throughput
is frequently first on the priority list—but it may soon take
second place to walkaway time. There’s no getting around it:
“There’s fewer and fewer staff to do more and more work,”
says Denise Pastore, Bayer clinical chemistry marketing manager.
“And the med lab tech schools aren’t really filling
up, so there’s nobody to replace them.”
With the instruments
in the latest lineup of chemistry analyzers for medium- and high-volume
labs, manufacturers continue to provide high throughput and extensive
menus. But the technologist and technician shortage has turned the
focus to new features designed to make the most of workers’
time and abilities.
Labs are using
automated systems to skirt the personnel shortage, says Dade Behring
marketing manager Bonita Kushernick, but she cautions that sample
accuracy can be sacrificed when replacing technologists with robotics.
“These systems decrease the technologist’s involvement
with individual samples,” she says, “and sample interferences
can easily be missed.” Dade Behring’s Dimension RxL
Max, introduced late last year, offers labs “smart processing”
of samples and testing for common
meanwhile, hopes to conserve staff time through instrument standardization.
“There are several hospital group labs that have a mix of
our AU400e, AU640e, and AU2700 analyzers,” says Olympus Diagnostic
Systems Group marketing director Bruce Gernaey, “and they
are capable of moving staff from site to site depending on their
personnel needs. The analyzers all have the same user interface,
the same standard values; they use the same reagents, the same controls.
It decreases your training time.”
Labs can look
for another labor-saving feature on Olympus analyzers later this
year: device relationship management. “This is actually connectivity
of analyzers through the Internet through the hospital network to
an Olympus server,” Gernaey says. “There’s continuous
monitoring of the instrument’s sensors, and we can track it
over a long period of time and see if certain shifts start to take
place.” If the manufacturer detects a possible problem with
the instrument, it can take action before a lab worker has to spend
time on maintenance.
director of product management marketing for Beckman Coulter, agrees
that remote diagnostic capabilities, available on several Beckman
Coulter instruments, can conserve worker hours. “Recently,
one lab director shared with us a story about how our ProService
remote diagnostic technology helped with the labor shortage in his
lab. Previously, every time an instrument went down, he had to take
people off the floor and move them to perform maintenance on the
instrument,” Heibel says. “Now he’s saving hours
and hours of technologist time by having this technology in place.”
to use worker time more efficiently, says Heibel, is to eliminate
a time-consuming, repetitive task: uncapping tubes. “When
workers do that in the lab, it can be several hundred samples per
hour,” he points out. “And when you’re doing anything
that repetitive, you always have the opportunity for injury.”
Beckman Coulter’s Synchron LX20 Pro chemistry analyzer and
LXi 725 chemistry-immunoassay system “are the only such systems
on the market to feature closed-tube sampling,” says Heibel.
“All a worker has to do is take the tube and drop it into
the instrument. You’re saving hours of tech time and ensuring
a safer work environment.”
But amid this
flurry of features targeting the lab worker shortage, manufacturers
aren’t neglecting the other needs of medium- and high-volume
laboratories. Abbott’s newest analyzer, the Architect ci8200,
features multidimensional sampling technology designed to maximize
throughput and reduce repeat test time. With the new technology,
“the samples aren’t processed in a line; they’re
elevated and immediately moved to the location that the test needs
to be processed within the system,” says global marketing
manager Dan Stredler. “The unique retest sample handler allows
operators to easily access sample tubes and move them to other workstations.
There’s no hindrance—for either operator or instrument—to
any access to any tube at any time.”
Advia 1650 and 2400 analyzers have several features designed to
conserve laboratories’ resources while maximizing their test
options. “We store over 32,000 tests photometrically on our
systems because of the microvolume technology we use,” says
Pastore. “We also have 90,000 ISE tests that we guarantee,
which provides a tremendous amount of walkaway capability.”
She adds, “The reagent consumption is minimal on the 1650
and even less on the 2400.”
Diagnostics will soon offer labs “improved labor optimization
and advanced result security” with a new product offering,
says Christine Forst, marketing product manager for clinical chemistry.
She’s looking forward to FDA clearance of the Vitros 51FS
analyzer later this year. “We are enhancing our current menu
offering with what is being called MicroTip technology. This technology
increases our menu offering while still not requiring any plumbing.
This continues to be a benefit because you don’t have to be
hooked up to a major water system. You can literally unplug the
system, move it, and plug it back in. You don’t have to build
a lab around it,” she says.
