Best Practice Recommendation from American Clinical Lab Assoc.

The American Clinical Laboratory Association (ACLA) has developed a Best Practice Recommendation for administrative sex and clinical patient gender used for laboratory testing and reporting. Please add the hyperlink below to the "Limitations, Dependencies, and Preconditions for Consideration" section, referencing ACLA's guidance document.


Need Sex Assigned at Birth

Administrative sex is used to indicate the sex a person has listed with their insurance company. Administrative sex and sex assigned at birth are not always the same. If someone legally changes their sex or the sex listed with their insurance company is different, then their administrative sex and sex assigned at birth no longer align. Therefore, it is necessary to ask both administrative sex and sex assigned at birth to accurately identify all transgender/GenderQueer patients. When insurance companies accept both sex assigned at birth and gender identity, then administrative sex will no longer be necessary.
