According to ASHI standards (2005), which information MUST be included on an HLA typing report?

The inclusion of the laboratory's address on an HLA typing report is essential for several reasons. It provides a clear point of contact for the results and verifies the legitimacy of the report. This transparency ensures that healthcare providers and patients can confirm the origin of the results, allowing for proper follow-up or consultation if necessary. The laboratory's address also contributes to the traceability of the report, which can be critical in the context of clinical care, especially when dealing with transplant patients who require precise HLA matching.

While the other options may contain relevant information, they do not carry the same requirement as stipulated by ASHI standards. The names of all directors and supervisors, while important for quality assurance, do not need to be included for the report's validity. The IMGT library used for allele assignments is valuable for technical reproducibility, but not mandated by these standards. Lastly, a patient's diagnosed disease state can be pertinent for clinical context but is not a mandatory component for reporting HLA typing results as per ASHI.
