I am Giuseppe Lippi.
I am a full professor of
clinical biochemistry at
the University of Verona,
and I'm also a member of
the EFLM working group on
the pre-analytical phase.
I would like to express
my sincere gratitude
for the honor of
being invited to deliver
this focused lecture on
the pre-analytical phase,
an important and often
overlooked topic
in laboratory medicine.
It is a privilege to
be here today sharing
insights on all aspects
of laboratory medicine
that plays a crucial
role in ensuring
the accuracy and reliability
of our diagnostic processes.

The pre-analytical phase,
although frequently
underestimated,
is the foundation upon which
the rest of the testing
process depends.
Without a deep understanding
of its complexities
and challenges,
the quality of our work
can be compromised,
affecting not only
the accuracy of
test results but also
patient outcomes.
As we explore this
topic together,
I hope to shed light
on the significance
of this phase and the steps
we can take to improve it.

Before delving into
the specific issues
related to the
pre-analytical phase,
it is important to briefly
revisit the broader context of
the total testing process
as was originally
conceptualized by George
Lundberg in the early 80s.
Lundberg's model portrays
the testing process
as a continuous
loop beginning with
the clinical question process
in the physician's brain and
ultimately returning
to the same point
after passing through
the pre-analytical,
analytical, and
post-analytical phases.
This cyclical nature emphasizes
the critical role
that each phase
plays in the overall
diagnostic journey.
The pre-analytical phase,
as we commonly define it,
encompasses a series of
crucial activities
that begin with
test ordering and
continue through
the preparation of the
sample before testing.
This phase sets the stage for
the accuracy and reliability
of the entire
diagnostic process.
However, it is important
to recognize that errors
can occur at any stage
throughout the
interior testing loop.
While the frequency of
these errors may vary,
they have the
potential to impact
the quality of test results
across the entire process.
Understanding this
continuous cycle
and the opportunities for
errors are essential
for improving
the overall diagnostic
accuracy and patient care.
