A Step-by-Step Guide to the Autopsy Process
Understanding what happens during an autopsy can help families feel more informed and prepared, whether an autopsy has been ordered by authorities or they are considering requesting a private examination. While the specifics can vary by jurisdiction and provider, the fundamental process follows a well-established medical protocol designed to be thorough, respectful, and scientifically rigorous.
Before the Autopsy: Authorization and Preparation
Authorization
Before an autopsy can proceed, proper authorization must be obtained. For forensic autopsies ordered by a medical examiner or coroner, no family consent is needed — the authority to perform the examination comes from the government’s legal jurisdiction over the case. For private autopsies, the legal next of kin must provide written authorization.
The order of next-of-kin authority typically follows this hierarchy: surviving spouse, adult children, parents, adult siblings, and then other relatives or the person designated by the court.
Case Review
Before beginning the physical examination, the pathologist reviews all available information about the decedent. This may include:
- Medical records and history
- Circumstances surrounding the death
- Scene investigation reports (in forensic cases)
- Medications the person was taking
- Any relevant family medical history
- Photographs from the scene (in forensic cases)
This background information provides important context that guides the pathologist’s examination and helps them identify areas requiring special attention.
Step 1: External Examination
The autopsy begins with a thorough external examination of the body. This step is conducted with meticulous attention to detail and is documented with photographs, measurements, and written notes.
During the external examination, the pathologist evaluates:
- General appearance: Overall condition, body habitus, apparent age, nutrition, and hydration status
- Identifying features: Height, weight, hair color, eye color, scars, tattoos, birthmarks, and other distinguishing characteristics
- Evidence of injury: Wounds, bruises, abrasions, burns, or other signs of trauma are carefully measured, described, and photographed
- Signs of medical treatment: Surgical scars, IV sites, catheter sites, or evidence of resuscitation efforts
- Evidence of disease: Skin lesions, jaundice, edema, or other visible signs of medical conditions
- Clothing and personal effects: In forensic cases, clothing is examined for damage, stains, or other evidence before removal
In some cases, the external examination alone may provide sufficient information, and a limited or partial autopsy may be appropriate. However, a complete autopsy includes internal examination as well.
Step 2: Internal Examination
The internal examination is the most detailed phase of the autopsy. The pathologist uses standard surgical techniques to access the body cavities and examine each organ system.
The Y-Incision
The pathologist makes a Y-shaped incision from each shoulder to the lower end of the breastbone, then straight down to the pubic area. This provides access to the chest and abdominal cavities. The incision is designed so that it can be completely concealed by clothing and does not affect the appearance of the face, neck, or arms.
Chest and Abdominal Organs
The pathologist systematically removes and examines each organ:
- Heart: Examined for evidence of coronary artery disease, valve abnormalities, cardiomyopathy, congenital defects, or signs of heart attack. The coronary arteries are opened and inspected. The heart is weighed and measured.
- Lungs: Evaluated for pneumonia, blood clots (pulmonary embolism), tumors, chronic disease, or signs of drowning or aspiration.
- Liver: Assessed for cirrhosis, fatty liver disease, tumors, or toxicological effects.
- Kidneys: Examined for disease, stones, or abnormalities that may indicate systemic conditions.
- Gastrointestinal tract: Evaluated for ulcers, tumors, bleeding, or other pathology. Stomach contents are noted, which can sometimes help establish a timeline.
- Spleen, pancreas, adrenal glands: Each examined for disease or abnormalities.
- Reproductive organs: Examined as appropriate, particularly in cases where relevant to the cause of death.
Brain Examination
To examine the brain, the pathologist makes an incision across the top of the head from behind one ear to the other. The scalp is reflected forward and backward, and the skull cap is carefully removed. The brain is then removed, weighed, and examined for hemorrhage, tumors, swelling, signs of infection, or degenerative disease.
In some cases, the brain may be preserved in formalin for a period of two to four weeks to allow proper fixation before detailed sectioning and microscopic examination. This is particularly common when neurological conditions are suspected.
Step 3: Sample Collection
Throughout the autopsy, the pathologist collects various samples for further analysis:
- Tissue samples: Small sections from each major organ are preserved in formalin for microscopic examination (histology)
- Blood: Collected from multiple sites for toxicology testing
- Urine: Tested for drugs and metabolites
- Vitreous fluid: The fluid from the eye is collected, as it is less susceptible to postmortem changes and provides reliable chemical analysis
- Bile and gastric contents: May be tested for drugs and poisons
- Hair and nail clippings: Can reveal long-term exposure to certain substances
Step 4: Laboratory Analysis
After the physical examination, collected samples are sent to specialized laboratories for further testing:
Histology (Microscopic Examination)
Tissue samples are processed into thin slices, placed on glass slides, stained with special dyes, and examined under a microscope. This can reveal cellular-level changes caused by disease, poisoning, or injury that are not visible to the naked eye.
Toxicology
Blood, urine, and other fluids are tested for the presence of drugs (prescription, over-the-counter, and illicit), alcohol, poisons, and other substances. Toxicology results typically take four to eight weeks to complete, and sometimes longer for complex panels.
Additional Testing
Depending on the case, additional testing may include microbiology (to identify infections), genetic testing, neuropathology (specialized brain examination), or biochemical analysis.
Step 5: Body Restoration
After the examination is complete, the body is carefully restored. Organs may be returned to the body cavities, and all incisions are closed with sutures. The pathologist takes care to ensure that the body’s external appearance is preserved as much as possible, allowing for an open-casket funeral if the family desires.
The body is then released to the funeral home designated by the family. The pathologist or their office will communicate with the funeral director about any relevant details regarding the examination.
Step 6: The Autopsy Report
The final autopsy report is a comprehensive document that includes:
- A summary of the decedent’s medical history and circumstances of death
- Detailed findings from the external and internal examinations
- Results of all laboratory testing
- Microscopic findings from tissue analysis
- The pathologist’s determination of the cause of death
- The manner of death (natural, accident, homicide, suicide, or undetermined)
- Any contributing factors
Timeline for Reports
Preliminary findings are often available within a few days of the autopsy. However, the final report — which includes all laboratory results and microscopic analysis — may take several weeks to several months to complete. Toxicology testing is often the factor that delays the final report.
Respecting the Decedent
It is important for families to know that autopsies are conducted with the utmost respect and professionalism. Forensic pathologists are trained medical professionals who understand the gravity of their work and treat every case with dignity. The examination follows established medical protocols, and the body is handled with care throughout the entire process.
