History Main / RapidDNATest

* One arc of ''ComicBook/{{Transmetropolitan}}'' introduces a new device called a "G-reader" that can read someone's genome from a distance. It's first used by Spider to indite a politician in a porn ring, and then by a bunch of skinheads to find someone with an unpopular genotype and kill him. [[spoiler: Spider later uses one to bring down the Smiler.]]

* Cale Tucker from ''WesternAnimation/TitanAE'' receives a ring from Captain Korso, made by his DisappearedDad, Doctor Tucker. This wedding band-sized bauble takes only seconds to analyze Cale's [=DNA=], and create a star map within Cale's hand (it doesn't hurt).

* The film adaptation ''Film/JudgeDredd'' of the comic book has Dredd carry the Lawgiver as his sidearm. In addition to voice-activated load switching, the Lawgiver can also take a [=DNA=] reading from its wielder, and deliver a lethal shock to any unauthorized user. It also takes the judge's [=DNA=] data, and encrypts the sequence onto the round fired, effectively signing the judge's handiwork, all within the few moments between unholstering the weapon and discharging it.
* ''Film/Terminator3RiseOfTheMachines'': The T-X can scan DNA in blood samples using its mouth.

* Tricorders in ''Franchise/StarTrek'' can usually scan DNA samples.
* ''Series/{{Andromeda}}'': The lineage-obsessed Nietzscheans tend to carry DNA scanners on them, and in "Music of a Distant Drum" a DNA biometric lock is one of the three locks on Tyr's safe. The High Guard's force lances have similar biometric security on them.
* In ''Series/AlteredCarbon'' Kovacs' expense account is tied to his sleeve's genetic profile, so he usually makes payments by slapping his saliva or blood on the register.
* In ''Series/{{Castle|2009}}'', Castle often uses his connections to get lab tests of various things related to the case he's helping with bumped in priority so that the results come back in a matter of hours rather than weeks.

* In ''VideoGame/EscapeFromButcherBay'' the guards have DNA-locked assault rifles that shock Riddick if he tries to pick one up.
* In ''VideoGame/HeavyRain'', [[FBIAgent Norman Jayden's]] ARI sunglasses can scan DNA instantly.
* In ''VideoGame/DetroitBecomeHuman'', [[RidiculouslyHumanRobots Connor]] can scan DNA samples by putting them in his mouth.

* In the pilot of ''WesternAnimation/{{Futurama}}'', Fry and the Professor are confirmed to be related by sticking their fingers into a machine that lights up green and dings a minute later.
* {{Parodied|Trope}} in ''WesternAnimation/TheSimpsons'' in "[[Recap/TheSimpsonsS7E1WhoShotMrBurnsPartTwo Who Shot Mr. Burns? (Part Two)]]". Chief Wiggum presents an eyelash for DNA analysis, and the technician warns that it takes eight to ten weeks. Then Wiggum bribes him with a carton of cigarettes, and the technician says "Did I say 'weeks'? 'Cause I meant 'seconds'."
* The Ringmaster from ''WesternAnimation/LoonaticsUnleashed'' has a device that performs LegoGenetics on target subjects, including a random boy attending his CircusOfFear. The Ringmaster captures all six Loonatics, and within minutes has computed their complete genomes. That's complete sequencing on two rabbits, one duck, one coyote, one roadrunner and one Tasmanian devil.

'''Technician:''' Whoa, whoa, whoa. That takes eight to ten weeks.\\
''[Chief Wiggum sighs and bribes the technician with a large carton of cigarettes.]''\\

->'''Technician:''' Woah, nice eyelash. Yours?\\

'''Technician:''' Woah, woah, woah. That takes eight to ten weeks.\\

* The central technology behind the plot of ''Film/{{Gattaca}}'' is DNA scanners that can determine one's identity from a drop of blood or urine in seconds and indicate whether a person has any genetic disorders. This makes laws against genetic discrimination impossible to enforce.

'''Technician:''' Woah, woah, woah. That takes eight-to-ten weeks.\\
'''Chief Wiggum:''' Sigh. [Bribes technician with a large carton of cigarettes.]\\

* Parodied on ''WesternAnimation/TheSimpsons'' in the second half of "[[Recap/TheSimpsonsWhoShotMrBurns Who Shot Mr. Burns]]". Chief Wiggum presents an eyelash for DNA analysis, and the technician warns that it takes eight to ten weeks. Then Wiggum bribes him with a carton of cigarettes, and the technician says "Did I say 'weeks'? 'Cause I meant 'seconds'."

In real life, DNA fingerprinting takes a minimum of a few hours, more often months given the backlog most labs have, and requires a whole array of different devices and chemicals. However, in fiction it's not uncommon to have devices that can read DNA as quickly as a biometric scanner.

'''Chief Wiggum:''' Sigh. [Hands technician a large carton of cigarettes.]\\

'''Technician:''' Did I say weeks? 'Cause I meant seconds.

** Tau battlesuits include DNA scanning to prevent {{Gundam Jack}}ing, as one human found out when he tried to steal one and was instantly fried.

* In ''Series/StargateAtlantis'', Ancient technology comes in two types: technology that can be used by anyone and technology that can only be initialised by humans with a very specific gene that humans have nicknamed 'the [[{{Precursors}} Ancient]] gene'. Technology can scan DNA to detect this gene instantaneously. Once the SGC became aware of the existence of, and need for, this gene, they made sure as many people as possible who possessed the gene was assigned to the Atlantis expedition. They also found a way to use gene therapy to give the gene to people who didn't possess it, although it only has a 48% success rate. All key systems in the city of Atlantis require initialisation, but once initialised can be used by anyone. The Puddle Jumpers, however, can only be used by someone who possesses the gene, so very few people can fly them as they are habitually switched off when not in use and therefore require initialisation every time they're switched on. Atlantis also possesses biosensors that can constantly scan in real time the people in the city and tell the difference between humans and Wraith, and also identify the presence of disease-causing pathogens which can instantly send the entire city into lockdown. There are members of the Pegasus Galaxy who also possess the Ancient gene, but they are few in number and at least two Royal Familities owe their dynastic reigns to the fact they possess the gene.

* In ''Series/StargateAtlantis'' nearly all [[{{Precursors}} Ancient]] technology only works for humans with a specific marker gene inherited from them. Which includes a fair number of the expedition, and the royal families of at least two Pegasus galaxy worlds.
