GuidelineScopeandCharter
GUIDELINE DRAFT TITLE: Laboratory Detection and Initial Diagnosis of Monoclonal Gammopathies
PROJECT CHARTER: The scope of the project is focused on pathology-related questions
related to the initial diagnosis of monoclonal gammopathies, beginning with how clinicians
should order for testing when monoclonal gammopathies are suspected and ending with how
pathologists should communicate the results of testing back to the clinician.
SCOPE: A primary goal of this guideline would be evidence-based recommendations for the
laboratory detection and initial diagnosis of monoclonal gammopathies. The scope includes
testing modalities in peripheral blood and urine, and excludes testing on bone marrow. The
scope will also include the reinforcement of the International Myeloma Working Group “Criteria
for Diagnosis of Multiple Myeloma” for testing and reporting.
BACKGROUND: The process for the detection of monoclonal gammopathies is highly
complex. To obtain an accurate diagnosis, diagnostic data must be compiled from several areas
of the laboratory (eg, total protein, immunoglobulin levels, gel or capillary electrophoreses
patterns).
Key Questions
What specimens are useful to detect MGs?
What are the appropriate tests needed to accurately detect and quantify MGs?
What information should be included in the laboratory order? And which laboratory testsare best used in which patients? What appropriate ancillary testing should berecommended?
TARGET AUDIENCE: The target audience of the evidence-based guideline is pathologists,
hematologists, clinicians, clinical laboratory directors, and clinical laboratory scientists.

Designation Description
High There is high confidence that available evidence reflects true effect. Further research
is very unlikely to change the confidence in the estimate of effect. Included studies
will be of high or intermediate quality.
Moderate There is moderate confidence that available evidence reflects true effect. Further
research is likely to have an important impact on the confidence in estimate of effect
and may change the estimate. Included studies will be of intermediate or low
quality.
Low There is limited confidence in the estimate of effect. The true effect may be
substantially different from the estimate of the effect. Included studies will be of low
quality.
