Complete Blood Count (CBC)
Biometría hemática completa
Also: Biometría hemática completa (BHC) (regional variant)
What it means
A complete blood count, or CBC, is a group of blood tests that measure the number and size of the different cells in the blood. A CBC measures red blood cells, which carry oxygen from the lungs to the rest of the body; white blood cells, which fight infections and other diseases; and platelets, which stop bleeding by helping blood to clot. It also measures hemoglobin, an iron-rich protein in red blood cells; hematocrit, the amount of whole blood that is made up of red blood cells; and mean corpuscular volume (MCV), the average size of the red blood cells. A complete blood count is often part of a routine checkup. Other names MedlinePlus gives for it are full blood count and blood cell count.

Spanish-language health sources use several names for this one test. Biometría hemática completa, with the abbreviation BHC, appears in a MedlinePlus en español encyclopedia article about another subject, in a list of exams that may be done. MedlinePlus en español titles its own page on the test conteo sanguíneo completo, abbreviates it CSC, and lists recuento sanguíneo completo and hemograma completo as other names. Its encyclopedia article begins with un hemograma o conteo sanguíneo completo (CSC).
The National Cancer Institute's Spanish dictionary enters the test as recuento sanguíneo completo and says it is also called cuadro hemático, hemograma, recuento de células sanguíneas completo, recuento sanguíneo and RSC. The abbreviation therefore changes with the name: BHC, CSC or RSC in Spanish, and CBC in English. Biometría is feminine, as the adjectives hemática and completa show, while conteo, recuento and hemograma are written with the masculine article un in these sources.
