High-density lipoprotein (HDL)

High-density lipoprotein is one of the five major groups of lipoproteins. Lipoproteins are complex particles composed of multiple proteins which transport all fat molecules around the body within the water outside cells.

Human chorionic gonadotropin (hCG)

Human chorionic gonadotropin is a hormone for the maternal recognition of pregnancy produced by trophoblast cells that are surrounding a growing embryo, which eventually forms the placenta after implantation.

Hypertext Transfer Protocol Secure (HTTPS )

A protocol where encrypted HTTP data is transferred over a secure connection.

The International Organization for Standardization is an international standard-setting body composed of representatives from various national standards organizations. The organization develops and publishes worldwide technical, industrial, and commercial standards.


JavaScript Object Notation (JSON)

A standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications.

JSON Web Token (JWT)

An open standard for securely transmitting information as a JSON object. Tokens are signed either using a private secret or a public/private key.


Low-density lipoprotein (LDL)

Low-density lipoprotein is one of the five major groups of lipoprotein that transport all fat molecules around the body in the extracellular water.


Multipurpose Internet Mail Extensions (MIME)

An Internet standard that extends the format of email messages to support text in character sets other than ASCII, as well as attachments of audio, video, images, and application programs.


National Provider Identifier (NPI)

OAuth 2.0

The OAuth 2.0 authorization framework is a protocol that allows a user to grant a third-party website or application access to the user's protected resources, without necessarily revealing their long-term credentials or even their identity.

OBX segment

The OBX segment is used to transmit a single observation or observation fragment. It represents the smallest indivisible unit of a report. The OBX segment can also contain encapsulated data, for example, a CDA document or a DICOM image. Its principal mission is to carry information about observations in report messages.



The set of observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.

Primary Care Physician OR Primary Care Provider (PCP)

  • Primary Care Physician: A physician (Medical Doctor) who directly provides or coordinates a range of health care services for a patient. Such physicians are specifically trained to provide comprehensive primary care services through residency or fellowship training in acute and chronic care settings.
  • Primary Care Provider: A physician, nurse practitioner, clinical nurse specialist, or physician assistant, as allowed under state law, who provides, coordinates, or helps a patient access a range of health care services.

Protected Health Information OR Personal Health Information (PHI)

Under HIPAA, PHI is considered to be any identifiable health information that is used, maintained, stored, or transmitted by a HIPAA-covered entity – a healthcare provider, health plan or health insurer, or a healthcare clearinghouse – or a business associate of a HIPAA-covered entity, concerning the provision of healthcare or payment for healthcare services.


A HTTP method that is used to create a resource.


A HTTP method used to update a resource. If the resource doesn't exist, it creates a new resource.


Reverse transcription-polymerase chain reaction (RT-PCR)

The reverse transcription-polymerase chain reaction is a laboratory technique combining reverse transcription of RNA into DNA and amplification of specific DNA targets using polymerase chain reaction. It is primarily used to measure the amount of a specific RNA.


Secret access key

A key that is used with the access key ID to cryptographically sign programmatic AWS requests. Signing a request identifies the sender and prevents the request from being altered.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)

A strain of coronavirus that causes COVID-19, the respiratory illness responsible for the COVID-19 pandemic.

Sexually transmitted diseases (STD)

Uniform Resource Locator (URL)

A Uniform Resource Locator, colloquially termed a web address, is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it.



Webhooks allow one program to send data to another as soon as a particular event occurs. They deliver real-time updates to your application as soon as the updates are available, and are less resource intensive than APIs.
