method to analysed body fluid
Answers
Laboratory testing can be performed on many types of fluids from the body other than blood. Often, these fluids are tested instead of blood because they can give more direct answers to what may be going on in a particular part of the body.
Some body fluid analyses include:
Urinalysis
Semen Analysis
Sweat Chloride
Fetal Fibronectin (fFN)
Amniotic Fluid Analysis
CSF Analysis
Synovial Fluid Analysis
Pleural Fluid Analysis
Pericardial Fluid Analysis
Peritoneal Fluid Analysis
Samples are usually obtained through collection of the fluid in a container (e.g., urine, semen) or by inserting a needle into the body cavity and aspirating with a syringe a portion of the fluid (e.g., CSF, pericardial fluid). For additional general information on how various samples are collected, see Collecting Samples for Testing.
Once a sample is obtained, a variety of tests may be performed, including chemistry tests, microscopic examinations, genetic tests, and infectious disease tests.
For certain body fluids, including pleural, pericardial, and peritoneal fluids, it is important to determine through testing whether the fluid is a transudate or an exudate because it can help diagnose the disease or condition present.
