Health reference: care models, costs, labs

Plain-language definitions of the care models, costs, and lab tests that come up when you look for a clinician who takes time to find causes.

How to use these health guides

Start with the question you want answered. Each guide explains the terms, links to its sources, and suggests questions for a clinician. Use it to prepare for a conversation about your care; it cannot diagnose your symptoms or choose treatment for you.

How to use this page

This section is a glossary. Each page defines a term you meet while looking for care: a practice model, a kind of cost, or a lab. The definitions are plain language, with the sources the page checked. They are here so a longer guide does not have to explain the same word every time.

Use a reference page when a word is in the way. Then go back to the guide that sent you, or to the approach or condition page that matches your question. A definition is not advice to order a test or to join a practice. It does not say what your result means.

The list below is every reference page published in this section. Titles are the terms. Descriptions under the titles say which idea the page covers. If the term you need is not listed, it does not have a page yet. It may still be explained inside a longer guide.

Sources and dates sit on each page. A definition that was accurate on the date checked can be overtaken by a new name for the same idea. If you have the newer source, the corrections policy is the way to send it, along with the address of the page that should change.

Treat this hub as an index, not as a second copy of the glossary. The sentences above say how to use a definition. The cards are the index. Open a card when you need the term itself, its sources, and the date the page was checked.
