Welcome to
the Interpretive Guide. This Guide provides information relating to test
selection, utilization, and interpretation. The Guide is continually updated
by adding new information and modifying posted information. All information
is based on peer-reviewed publications, practice guidelines, or other
reputable sources and is intended to be without promotional considerations.
Reference
ranges are provided for your convenience and are based on Quest Diagnostics
data or published references (where cited). These ranges can serve as a
guideline; however, interpretation of patient results should be based on the
ranges provided in the patient report.
Included in the Interpretive Guide are four types of information:
Test highlights and summaries provide a review of clinical use and
background, methodology, specimen requirements, and interpretation of the
test.
Test guides
provide testing algorithms or other information that assists in appropriate
test selection.
Technology
guides compare multiple technologies provided for the same or similar
analytes.
Clinical focus pages focus on specific diseases or
conditions, providing detailed information on what tests are available, how
they are incorporated into clinical practice, and what the results mean.
What's New
•
The
Genomic
Alterations, Oncology, Clarisure® CGH test uses
microarray comparative genomic hybridization (CGH) technology to detect
genetic gains and losses throughout the genome. Clinically, it is used as
an adjunct to karyotyping and fluorescence in situ hybridization (FISH)
for detecting chromosome abnormalities that may have prognostic
significance for patients with hematologic malignancies.
•
The
ColoVantage™
(methylated Septin 9) test detects circulating methylated DNA from the
SEPT9 gene. Such methylated DNA has been associated with colorectal
cancer.
•
The
Inflammatory Bowel Disease Differentiation Panel may be helpful in
differentiating between ulcerative colitis (UC) and Crohn disease (CD) in
some patients with inflammatory bowel disease (IBD).
•
The
Antithrombotic Therapy clinical focus provides laboratory test
selection and interpretive information to facilitate optimal drug dosing
and therapeutic monitoring of 5 common antithrombotic therapies.
