The results of a blood test are typically available within 24 hours of taking the blood sample, but the wait depends nevertheless on the diagnosis and which elements of the blood are being looked for. Blood samples can be analyzed for several hundred different possible variables, with blood cholesterol
, glucose, hormones, red blood cell
, and white blood cell levels, as well as the HIV test all being among the most commonly performed. The expertise of a healthcare professional is required to be able to reliably read and translate these results in the context of a doctor's appointment. Furthermore, each laboratory uses different machines and calculates from different "normal" values, thus providing blood test results that can present elevated or decreased levels in comparison with "normal" in the absence of any disease or condition.
