The Denver Developmental Screening Test ( DDST) was introduced in 1967 to identify young children, up to age six, with developmental problems. A revised version, Denver II, was released in 1992 to provide needed improvements. These screening tests provide information about a range of ages during which normally developing children acquire ...
The World Health Organization (WHO) COVID-19 Case Definition states that a person with a positive RAT (also known as an antigen rapid diagnostic test or Antigen-RDT) can be considered a "confirmed case of SARS-CoV-2 infection" in two ways. [10] First, the person with a positive Antigen-RDT could meet a "probable case definition" such as having ...
Point-of-care testing ( POCT ), also called near-patient testing or bedside testing, is defined as medical diagnostic testing at or near the point of care —that is, at the time and place of patient care. [1] [2] This contrasts with the historical pattern in which testing was wholly or mostly confined to the medical laboratory, which entailed ...
A test is done by taking a small scraping from a pill and placing it in the reagent testing liquid or dropping the reagent onto the scraping. The liquid will change colour when reacting with different chemicals to indicate the presence of certain substances. Testing with a reagent kit does not indicate the pill is safe.
A lateral flow test ( LFT ), [1] is an assay also known as a lateral flow device ( LFD ), lateral flow immunochromatographic assay, or rapid test. It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment. LFTs are widely used in medical diagnostics in ...

Rapid antigen test. A rapid antigen test ( RAT ), sometimes called a rapid antigen detection test ( RADT ), antigen rapid test ( ART ), or loosely just a rapid test, is a rapid diagnostic test suitable for point-of-care testing that directly detects the presence or absence of an antigen. RATs are a type of lateral flow test detecting antigens ...
A pregnancy test is used to determine whether a female is pregnant or not. The two primary methods are testing for the female pregnancy hormone ( human chorionic gonadotropin (hCG)) in blood or urine using a pregnancy test kit, and scanning with ultrasonography. [1] Testing blood for hCG results in the earliest detection of pregnancy. [2]
