Table. 4. Elements to include in the pharmacogenetic testing result report
Category Elements
Test request information

Reason for test request or test indication

Clinical diagnosis or relevant clinical information

Medication history

Demographic data (e.g., age, sex, ethnicity)

Test information

Type of specimen

Names of the gene(s) analyzed

Regions of target gene(s) included in the test (target alleles and/or variants)

Test method:

Assay principle

Indicate whether a laboratory-developed or commercially available kit was used, and whether the test was performed within the laboratory or by a referral laboratory

Test limitations:

Mention whether there are clinically significant genotypes that the test method cannot detect

Note any specific characteristics or limitations based on the test method

Test results

Types of detected genetic variants, corresponding alleles, and genotype results:

Describe genetic variants using standard nomenclature

Indicate whether the patient is heterozygous or homozygous for the variant

Provide the type of variant discovered

Relevant reference literature: when available, include allele frequency data in the target population/ethnicity

Description of expected phenotype: phenotype conversion

Interpretation and recommendation

Brief explanation of important drugs associated with the target gene

Discussion of the relevance of the results to the test indication

Description of the drug response related to the variants identified (e.g., sensitivity or resistance to chemotherapy)

If applicable, any cautions related to result interpretation

If applicable, recommendations for additional testing

Clinical application considerations, such as dose adjustment or the use of alternative drugs based on genotype

Citation of the appropriate references and publications associated with interpretation and recommendation

Additional elements required in the final report format

Interpretation and (electronic) signature of the laboratory director on the final report

Name and address of the laboratory, patient name, unique patient identifier, and date of birth (or age)

Include the name of the requesting physician and the affiliated institution; for requests from different institutions, add the name or contact information of the requesting organization

Date of specimen receipt and date of result report

Name of the testing personnel and (electronic) signature of the laboratory director who interpreted the results For tests referred from other laboratories, documentation must indicate the referral along with the (electronic) signature of the laboratory director from the requesting institution
