An autopsy report is a detailed medical document, often 20 or more pages long, that walks through every aspect of a person’s death in clinical language. If you’re reading one for the first time, it can feel overwhelming. The structure is predictable, though, and once you understand the main sections, the terminology, and how the conclusions connect to the evidence, the report becomes much more navigable.
How an Autopsy Report Is Organized
Most autopsy reports follow the same general sequence, regardless of where they were performed. The report opens with identifying information: the deceased person’s name, age, sex, date and time of death, and the date the autopsy was performed. It also names the pathologist who conducted the examination and usually includes a case number.
From there, the report typically moves through these sections in order:
- External examination: A head-to-toe description of the body’s surface, including height, weight, identifying features, and any injuries or marks.
- Internal examination: A detailed account of each organ system, including organ weights, the condition of tissues, and any abnormalities found during dissection.
- Toxicology: Lab results showing what drugs, alcohol, or other substances were present in the blood, urine, or other fluids.
- Histology (microscopic examination): Findings from tissue samples examined under a microscope.
- Cause of death and manner of death: The pathologist’s final conclusions, stated in formal terms.
Some reports also include radiology findings (X-rays taken before or during the autopsy), microbiology results if infection was suspected, and a narrative summary that ties all the findings together. Not every report contains every section. A straightforward natural death may have a shorter report than a complex forensic case.
The External Examination
This section reads like an extremely thorough physical description. The pathologist documents the body’s general condition, clothing (if relevant), and postmortem changes that help establish what happened after death. Two terms come up frequently here.
“Livor mortis” (sometimes just called “livor”) refers to the dark discoloration that settles in the lowest parts of the body after the heart stops pumping. Its location tells investigators whether the body was moved after death. “Rigor mortis” describes the stiffening of muscles, which follows a predictable timeline and helps estimate how long ago death occurred.
The external exam also documents every injury visible on the skin: bruises, cuts, gunshot wounds, surgical scars, needle marks, and any signs of medical intervention like IV sites or defibrillator marks. If you see the phrase “evidence of medical intervention,” it’s noting treatment that was attempted before death, not anything suspicious. The pathologist records the size, shape, color, and exact location of each finding, often using measurements in centimeters and anatomical landmarks that may sound unfamiliar. For example, “a 3.2 cm contusion on the left temporal region” simply means a bruise about an inch and a quarter wide on the left side of the head, above the ear.
The Internal Examination
This is usually the longest section of the report. The pathologist opens the body and examines every major organ system, describing what they see with the naked eye (called “gross examination”) and recording the weight of each organ. Organ weights matter because they reveal enlargement or atrophy. An unusually heavy heart, for instance, often points to long-standing high blood pressure or heart disease.
You’ll notice the report moves systematically through the body: the brain, the cardiovascular system, the lungs, the abdominal organs, and so on. For each organ, the pathologist describes the color, texture, size, and any abnormalities. A phrase like “within normal limits” (sometimes abbreviated WNL) means nothing unusual was found. “Unremarkable” means the same thing. These are good words to see if you’re looking for reassurance that an organ was healthy.
Conversely, terms like “congestion” (excess blood pooling in tissue), “edema” (fluid buildup), “adhesions” (abnormal tissue connections from old inflammation), or “atherosclerosis” (fatty buildup in arteries) flag problems. These aren’t always the cause of death, but the pathologist documents everything to build a complete picture. If a finding is severe enough to contribute to death, it will typically reappear in the final conclusions section.
Understanding Toxicology Results
The toxicology section lists every substance detected in the body along with its concentration, usually measured in the blood. This is where many readers get confused, because a number alone doesn’t tell you much without context.
Drug concentrations generally fall into a few categories. A “therapeutic” level means the amount you’d expect if someone was taking a medication as prescribed. A “subtherapeutic” level means the drug was present but at a concentration too low to have its intended effect. A “supratherapeutic” or “toxic” level means the concentration exceeded what’s considered safe, and at the extreme end, a “lethal” concentration indicates a level associated with fatal overdoses in published medical literature.
These ranges aren’t absolute, though. A concentration that’s lethal for one person may be tolerated by someone with a long history of use, because their body has built up tolerance. The pathologist considers these nuances when forming their conclusions. If you see multiple substances listed, the interaction between them often matters more than any single drug level. The report may note this, or the pathologist may address it in the narrative summary.
Alcohol is reported as blood alcohol concentration (BAC), which is the same scale used for legal intoxication. A BAC of 0.08 is the legal limit for driving in most U.S. states. Levels above 0.30 are generally considered life-threatening.
What Histology Tells You
The histology section describes what the pathologist found when examining thin slices of tissue under a microscope. This part of the report is often highly technical, but it serves a critical purpose: some conditions can only be diagnosed at the cellular level.
Inflammation of the heart muscle (myocarditis), certain types of blood clots that travel to the lungs (fat embolisms, amniotic fluid embolisms), and early-stage cancers are examples of findings that may look completely normal during the hands-on portion of the autopsy but show clear abnormalities under a microscope. Organs that appeared healthy during the internal exam, including the brain, lungs, heart, liver, and kidneys, can reveal significant disease when examined this way. Histology is especially important in cases where the cause of death wasn’t obvious from the external or internal exams alone.
Cause of Death vs. Manner of Death
These two terms look similar but answer different questions, and understanding the distinction is essential to reading the report’s conclusions correctly.
The cause of death is the medical condition, disease, or injury that started the chain of events leading to death. It’s stated in medical terms: “atherosclerotic cardiovascular disease,” “gunshot wound to the chest,” “acute fentanyl toxicity.” Reports often list the cause in a layered format, starting with the immediate cause (line a) and working backward to the underlying cause (lines b, c, d). For example, line a might read “pulmonary embolism” (a blood clot in the lungs), line b “deep vein thrombosis” (a clot in the leg), and line c “immobilization following hip fracture.” The bottom line is the root cause.
The manner of death describes the circumstances, and there are only five standard categories: natural, accident, suicide, homicide, or undetermined. “Homicide” in this context is a medical-legal classification meaning death at the hands of another person. It is not a legal finding of guilt or innocence. “Undetermined” is used when the evidence doesn’t clearly point to one category.
You may also encounter the term mechanism of death, which is the specific physiological event that caused the body to stop functioning: hemorrhage (blood loss), sepsis (overwhelming infection), or asphyxia (oxygen deprivation), for example. The mechanism explains how the cause of death actually killed the person.
Common Abbreviations
Autopsy reports are full of shorthand. Some of the most frequently used abbreviations include GSW (gunshot wound), HCVD (hypertensive cardiovascular disease), ASHCVD (arteriosclerotic hypertensive cardiovascular disease), and SIDS (sudden infant death syndrome). You’ll also see standard medical abbreviations like “cm” for centimeters, “g” for grams (used for organ weights), “ml” for milliliters, and “mg/dL” or “ng/mL” for drug concentrations. “AP” and “lateral” refer to the angles of X-ray images, front-to-back and side view respectively.
Preliminary vs. Final Reports
If you received a report quickly after the death, it may be a preliminary version. Preliminary results can be available within two to three days, but a full autopsy report typically takes about six weeks. Forensic autopsies, which involve deaths under suspicious or unusual circumstances, often take longer. The delay is usually due to toxicology testing, histology processing, or waiting for police investigation results.
A preliminary report may list the cause of death as “pending” or “deferred pending further studies.” This doesn’t mean something went wrong. It means the pathologist is waiting on lab results before making a final determination. The final report will include the completed toxicology, histology, and any other ancillary testing, along with the pathologist’s definitive conclusions.
How To Get a Copy
Access to autopsy reports varies by state. In some jurisdictions, they’re considered medical records with strict privacy protections. In Virginia, for example, only legal next of kin can request copies, and the law spells out a priority order: spouse first, then adult children, parents, adult siblings, and then other relatives. The request must be made in writing with the deceased person’s name, date of death, and the requester’s signature.
Other states treat autopsy reports as public records that anyone can request. You’ll need to check the laws in the state where the death occurred. In most cases, the request goes to the medical examiner’s office or coroner’s office that handled the case. Reports are generally only released once the case is finalized, so if the report is still pending, you may need to wait before a copy is available.
