What a CBC covers
What a complete blood count measures, how the sample is collected, and how to compare cash offers. No prices and no result interpretation.
Cash prices, where a sheet row exists, are on a separate page: CBC cash price page.
What it measures
A complete blood count (CBC) is a group of blood tests that measures the number and size of the different cells in the blood. MedlinePlus lists the components as red blood cells, white blood cells (total count), platelets, hemoglobin, hematocrit, and mean corpuscular volume (MCV). A CBC with differential also measures the number of each of the five major types of white blood cells.
The cash offer names the pieces that seller includes. Two offers can both say CBC and still list different lines. This page does not treat every CBC as one fixed panel.
Reference ranges vary by lab. This page does not interpret a result, and it does not say what a high or low number means. Ask your clinician.
How the sample is collected
Collection is a blood sample. A needle enters a vein, and the sample goes into the tube the order names. The visit is at a patient service center or another collection site the seller names. The cited pages do not give one visit length for every lab, so this page does not state one.
Prep and fasting
Prep, including whether to fast, is set by the order and by the seller. This page does not state prep steps. A cash price page states prep only as the seller states it, with the date it was checked.
How long results usually take
The cited pages do not publish one result-release time that every lab uses. When you compare cash offers, use the window that offer states, and the date this site last checked that offer.
How to compare cash prices
Line up the same test name, the component list on the offer, the date the price was checked, any draw fee the offer states, and any physician-order fee the offer states. A missing fee stays missing. This page does not list amounts. See how to compare lab test prices.
