Digital polymerase chain reaction (digital PCR, DigitalPCR, dPCR, or dePCR) is a biotechnological refinement of conventional polymerase chain reaction methods that can be used to directly quantify and clonally amplify nucleic acids strands including DNA, cDNA, or RNA.
False positive COVID-19 tests—when your result is positive, but you aren’t actually infected with the SARS-CoV-2 virus—are a real, if unlikely, possibility, especially if you don’t perform ...

BDORT as illustrated in patent 5188107 [1]. The Bi-Digital O-Ring Test (BDORT), characterized as a form of applied kinesiology, [2] is a patented alternative medicine diagnostic procedure in which a patient forms an 'O' with his or her fingers, and the diagnostician subjectively evaluates the patient's health according to the patient's finger strength as the diagnostician tries to pry them apart.
Clearblue home pregnancy test system 1985. Clearblue was introduced in 1985 with the launch of the first Clearblue Home Pregnancy Test system, which at the time was owned by Unilever. [4] It was the world’s first “rapid home test” that gave pregnancy test results in 30 minutes and allowed a woman to take a test before going to the doctor. [4]
This single-digit number is called the "digital root" of the original. If a number is divisible by 9, its digital root is 9. Otherwise, its digital root is the remainder it leaves after being divided by 9. A sanity test in which the above-mentioned procedures are used to check for errors in arithmetical calculations. The test is carried out by ...
Accuracy is measured in terms of specificity and selectivity. Test errors can be false positives (the test is positive, but the virus is not present) or false negatives, (the test is negative, but the virus is present). [179] In a study of over 900,000 rapid antigen tests, false positives were found to occur at a rate of 0.05% or 1 in 2000. [180]
The kinetoplast fluoresces if serum contains high avidity anti-dsDNA antibodies. This test has a higher specificity than EIA because it uses unprocessed DNA. Processed DNA can contain regions of ssDNA, allowing detection of anti-ssDNA antibodies, which can give false positive results. [1] [28]
