In media, there are two sorts of people who wear labcoats: scientists and medical doctors. As such, a character wearing a lab coat is a good indication that they're involved in either science (and/or Mad Science!), or a medical field. This is despite the fact that in real life doctors and scientists do not normally wear such coats unless there is a reason that they need to keep their clothes clean, and should definitely not wear them in public because they might expose people to dangerous substances. In media, this coat is almost always white. In Real Life, labcoats are often white, but also come in blue and green. These colors show stains well, which is the point - you need to know when to wash your coat.
A subtrope of the Labcoat of Science and Medicine is the Mad Scientist Lab Coat which is typically the Howie-style lab coat with the asymmetrical front panel and the high, stiff collar. This style of full-coverage lab coat, designed to minimize pathogen contact with street clothing, has long been associated with esoterically-minded scientists from Dr. Frankenstein to Dr. Horrible, and is pretty much a clear sign that its wearer doesn't care about such silly things as medical ethics boards while he Gets Shit Done. (It probably helps matters that to many viewers this style subliminally suggests a straitjacket.) Another marker of Science-Related Memetic Disorder is when the coat (Howie-style, or otherwise) is particularly ragged, tattered, stained with unknown substances and full of holes burned by acid, lightning or god knows what else; this is a clear sign that the wearer experiments with dangerous stuff, doesn't care about either safety or appearance.note
Naturally, this also makes a lab coat a very convenient costume for a person who's trying to appear intellectual, whether or not they actually are. This could include a Snake Oil Salesman, someone Feigning Intelligence, or of course an actor who plays a doctor on TV.
Supertrope to Dressed to Heal which also requires a stethoscope and a head mirror. Compare Einstein Hair, another classic visual cue that screams "Science person!" Also see Group-Identifying Feature. Nerd Glasses are technically optional but functionally may as well be a required accessory.

Any product with any sort of purported health benefit will have a doctor straight out of Central Casting giving it the stamp of approval, and almost invariably decked out in a white labcoat.

“You are pretty well informed, aren’t you?”
“You could say that,” Jered replied, curious and a little wary. He could make out the shape of two short swords underneath the open lab coat she was wearing, after all.
“I’m volunteering !” the redhead clarified. “I’m supposed to be a guard, not a nurse!

Knowing Johanna hasn't had that much experience with men, and making a shrewd guess as to what a scientifically-minded nerdy Wizard might appreciate in a love interest, more worldly friends get her into a white lab-coat and give her a clipboard to hold. Ponder Stibbons, visiting the A.M.U., is suitably entranced.
- Dr. Cockroach from Monsters vs. Aliens wears a lab coat, as any respectable Mad Scientist would.

Dornwinkle himself proves to be much more relaxed about this himself later on when he's shown perfecting his invisibility serum at home in his apartment in his civilian clothes.

- Skyfall. Lampshaded when Bond meets the new (and very young) Q.
Bond: You've got to be joking.

- In Kamen Rider Ex-Aid, all doctor characters wear white coat. Anyone (but one person) who does not has some reason like guilt or Evil Costume Switch.
- ER: Most of the doctoral staff that work directly with patients wear a white labcoat unless in surgery. This is in contrast to the nursing staff, who wear only scrub, and administration, who wear suits. The length of the labcoat becomes a minor plot point in a season 13 episode, when Pratt, the ER attending, buys a one for Tony Gates, a parademic-turned-medical student who is a bit full of himself. His confidence had led to many patients assuming he was more qualified than he was, and Pratt makes it a point to buy him a short labcoat, as this denotes his status as a medical student who is still learning. As opposed to a longer one that would indicate he was a resident or a full-fledged physician. This was, at one point, Truth in Television, though labcoats at all are becoming outdated.

- Wonder Woman: In "Anschluss '77", Wonder Woman transformed into a brown dress and tan heels and put on a lab coat that was available in order to disguise herself as Dr. Heinrich Von Klemper's assistant. Of course, the ruse didn't last long since the doctor had never previously had a stunningly gorgeous assistant. Her magic lasso worked fine, but it was unclear if she was wearing her belt of strength under the lab coat or whether it would work properly when worn this way. The scene implied that Wonder Woman retained her full abilities as it included Steve Trevor holding two Nazis prisoner - something he rarely could accomplish without Wonder Woman backing him up. Regardless, it's often overlooked that one of the many official Wonder Woman outfits from the series includes...a brown dress.

Given that he spends much of his time involved in gruesome surgical experiments or mixing up dangerous alchemical elixirs, it's also of practical use. Of course, this being Warhammer 40K, and Fabius being an amoral monster in league with the Infernal Powers, said labcoat is made from stitched together human skins.

When you arrive at Black Mesa East, Eli says, "We'll get you out of that hazard suit and into your lab coat where you belong." Black Mesa scientists really like their lab coats, it seems. Though, to their credit, Eli, Judith, and Magnusson aren't wearing them in the Half-Life 2 games — but Magnusson's assistant, Uriah (a vortigaunt), is wearing one.
