An autopsy is a medical examination of a body after death. Pathologists perform autopsies to try to find the specific cause and manner of death. There are two types of autopsies: forensic and clinical.

An autopsy is a medical examination of a body after death to find the cause — and sometimes manner — of death. A pathologist trained to perform autopsies thoroughly examines the inside and outside of the body.

The word “autopsy” comes from the Greek word “autopsia,” which means “to see for oneself.” People sometimes call an autopsy a post-mortem, especially in the U.K. “Post-” means “after,” and “mortem” means “death.”
There are two main types of autopsies based on the reason for them: forensic autopsies and clinical autopsies.
Forensic pathologists perform forensic autopsies (medicolegal autopsies) as a part of legal investigations. “Forensic” means “related to scientific methods of solving crimes.”
States in the U.S. and countries across the world each have specific legal criteria for when a death requires a forensic autopsy. But in general, this type of autopsy is typically necessary when a death is:
The legal authority that requires or directs a forensic autopsy varies across the world. Examples include the:

A hospital pathologist sometimes performs a clinical autopsy (pathological or hospital-based autopsy) in cases of natural death to find and/or better understand the cause of death. A natural death happens due to an internal factor that causes your body to shut down. Examples include cancer, a heart attack and an infectious disease. It means there was no external reason for the death, such as a fatal injury or drowning.
The deceased person’s next of kin (family members) may ask for this type of autopsy. Or a healthcare provider may ask the next of kin for their consent to do a clinical autopsy.
Pathologists can do autopsies on bodies any time after death. However, the sooner, the better. After 24 hours, organs and other body tissues start to deteriorate, which makes it more difficult to perform certain tests and assess their accuracy.
Forensic pathologists can still do autopsies on decomposed or exhumed (removed from burial in the ground) bodies. But the detail and extent of information (and/or evidence) they can gather may be limited.
A specialist called a pathologist performs autopsies. Pathology is the branch of medicine that involves the laboratory examination of samples of body tissues for diagnostic or forensic purposes.
Pathologists who perform autopsies are medical doctors. They have expansive knowledge and specific training on the human body. It usually takes about 11 to 13 years to become a pathologist.
You may hear or read that a medical examiner performs autopsies. The title of “medical examiner” is usually the job title of a forensic pathologist who works for a government.
The process of an autopsy can vary depending on the reason for it. Forensic autopsies are often very thorough, examining every part of the body. They also typically include crime scene investigation and toxicology — the branch of science that explores the nature, effects and detection of poisons.
Clinical autopsies may only investigate certain parts of the body. They typically don’t do toxicology as part of the autopsies.
In general, the steps of an autopsy may include:

The pathologist may need to keep some organs for further examination or retain organs as permitted on the consent form. Once they’ve completed all their examinations and tests, the pathologist will provide a detailed report.
The goal of all autopsies is to find the cause of death. But forensic autopsies have additional goals or objectives, including:
It usually takes a pathologist two to four hours to examine a body during an autopsy. They may be able to release preliminary (early) results within two to three days of the autopsy. But the full results of an autopsy typically take six weeks — or longer — to prepare.
Certain factors can extend the length of the results, like:

An autopsy report includes details of all the observations, examinations and tests of the body.
It typically states the cause of death and the general manner of death. Based on scientific and medical evidence, the pathologist lists the manner of death as one of five categories:
In some cases, a pathologist can’t find the cause of death despite a thorough autopsy. This is called a negative or obscure autopsy. Advanced laboratory techniques that become available in the future may help eventually determine the cause of death.
An autopsy report contains scientific observations and test results of a deceased person’s body and anything on their body. A forensic autopsy alone can’t confirm how a person died. The Court of Law in most countries has the final say on this matter. Detectives and other legal representatives use the information in forensic autopsies, along with other evidence that they’ve gathered, to infer how a death unfolded.
While pathologists have extensive knowledge and training, it’s important to remember that they’re human just like the rest of us. Like everyone else, they may make mistakes. Or they may not be able to uncover the exact cause of death. In some of these cases, family members or legal authorities may request a second autopsy of the body by a different pathologist.

Potential benefits of autopsies include:
There’s no charge for most clinical autopsies that pathologists perform at a hospital. Autopsies that fall under the jurisdiction of the medical examiner or coroner are also provided at no cost. There may be a charge for transporting a body to and from a hospital facility. In addition, you may have to pay for genetic testing of inherited conditions.
Autopsies are a critical part of the medical field — and justice. They can help expand medical knowledge and find the answers to the unknown. If your loved one needs an autopsy, know that a pathologist will handle their body with care. They’ll use their expertise to provide the medical answers that they can.
