Aegrotat

A certificate, a doctor's certificate, is a written statement from a physician or other medically qualified health care provider which attests to the result of a medical examination of a patient. It can serve as a "sick note" (documentation that an employee is unfit for work) or evidence of a health condition.

An aegrotat (/ˈiːɡroʊtæt/; from Latin aegrotat, meaning 'he/she is ill') or sick note is a type of medical certificate excusing a student's absence from school for reasons of illness.

Medical certificates are sometimes required to obtain certain health benefits from an employer, make an insurance claim, for tax purposes, or for certain legal procedures. Medical certificates are used to indicate eligibility of activity, such as the use of disabled parking. Medical certificates can also be used to describe a medical condition a person has, such as blindness. Medical certificates are often used to certify that someone is free of contagious diseases, drug addiction, mental illness, or other health issues.

Health criteria are often required when making an application for something, such as an eye examination to get a driver's license. Other times medical criteria are presented voluntarily by an applicant in a self-assessment, without either a doctor or access to the person's medical record. Specific health criteria or medical history are required for certain jobs.
