The Clonality (ID) Test is used to identify dominant DNA sequences in a high disease load diagnostic sample.
Identification of at least one dominant DNA sequence is a prerequisite to future monitoring of MRD. After the dominant DNA sequences has been identified utilizing the Clonality (ID) Test, subsequent monitoring of the associated clone(s) can be completed by ordering Tracking (MRD) Tests.

Page 1 of the report shows that dominant DNA sequences were identified from the submitted sample.
A more detailed description of the results for this sample can be found in the “Results Summary” section.
A summary of the criteria used to determine which DNA sequences are dominant and thus can be followed as markers of malignancy is provided at the bottom of the page for reference.
-
Page 2/3
Page 2 of the report shows detailed information relating to the sample including the actual rearranged DNA nucleotide sequence or sequences identified, the sample collection date, the receptor locus in which each dominant sequence was found, the specimen type analyzed, the frequency of the dominant sequence as a fraction of the total nucleated cells assessed, and the total number of cells carrying the rearranged DNA sequence.

Page 3 of the report provides more details on the immune repertoire of the analyzed sample, including the sample clonality, the number of sequences assessed for each locus, and the number of unique sequences assessed
The clonoSEQ B-cell Tracking (MRD) Report provides results based on analysis of the IgH, IgK and IgL loci as well as Bcl1 and Bcl2 translocations.
After the dominant DNA sequences has been identified utilizing the Clonality (ID) Test, subsequent monitoring of the associated clone(s) can be completed by ordering Tracking (MRD) Tests throughout treatment.

In this sample, residual disease (MRD) was detected by the clonoSEQ Assay. This is indicated by the “plus” sign as well as the language stating “Residual Sequences Detected” in the blue box on page 1 of the report.
Further down the page, the Results Summary states the actual number of sequences observed by the assay and the total number of nucleated cells assessed in the sample.
In the bottom third of the page, a chart provides a longitudinal view of the sample-level MRD result for the current sample as well as for past samples sent for clonoSEQ testing for this patient.
-
Page 2/4
Page 2 of the report shows detailed information relating to the current and previous samples including the actual rearranged DNA nucleotide sequence or sequences identified, sample collection dates the receptor locus which each dominant DNA sequence was found, the specimen type analyzed, the estimated sequence abundance (i.e., the number of residual clonal cells per million nucleated cells), and the 95% confidence interval for each MRD result.
A blue bar will be placed next to one of the sequences listed on this page to indicate that it is the sequence determining the MRD result for the current sample.

Page 3/4
Page 3 of the report displays the sequence-level information from Page 2 in a chart format. This “sequence-level MRD” chart provides a longitudinal view of results for each individual tracked sequence.
In addition to the sequence-level chart, this page lists the criteria used by the clonoSEQ Assay to define dominant sequences, as well as a summary of the assay method and limitations.
The appendix provides more details on the immune repertoire of the analyzed sample, including the sample clonality, the number of sequences assessed for each locus, and the number of unique sequences assessed.
-
Page 4/4
Page 4 of the report continues details on the immune repertoire of the analyzed sample, noting the limit of detection and limit of quantitation for each sequence tracked.
A glossary of terms and references relevant to the report is also provided on this page.
Within the glossary, the assay’s limit of blank, which is zero, is stated and defined.
The content of this page is intended primarily for healthcare professionals.
