However as most commercial chemistry reagents are only validated for serum plasma and urine by manufacturers individual laboratories have to validate testing with NSBF to comply with regulatory standards.
. The types of fluids most commonly examined in hematology are cerebrospinal CSF serous pleural and peritoneal and synovial. In vivo degradation and resorption of aliphatic polyesters is described as a loss of physical andor chemical integrity resulting from the interaction of a material with living tissue due to the hydrolysis process. However understanding the clinical utility of these analytes is critical because laboratories must address the analytic and clinical validation requirements while educating clinicians on proper test utilization.
Choose from 500 different sets of the body fluids chemistry flashcards on Quizlet. Clinical and Laboratory Standards Institute. Normal fluid is less than 35 mL volume highly viscous clear and colorless to light yellow.
The chemical composition of fluids in the various compartments is carefully regulated. Pleural and pericardial fluid. Your goals for learning are.
Body fluid testing for a number of analytes has been reported in the literature. The tonicity of body fluids is reflected by the serum sodium concentration which is a function of the bodys content of sodium and potassium more precisely the portion that is free in solution and not bound to proteoglycans in bone cartilage and connective tissue divided by its content of waterSerumsodiumconcentrationTotalbodyNaKTotalbodywater. The fluids in your body are composed of water and dissolved substances including electrolytes which are crucial for body function.
PH of ECF is 74 PH of ICF is 7. The CSF flows between the arachnoid mater and the pia mater in an area referred to as the subarachnoid space. National Center for Biotechnology Information.
Intracellular fluid contains large quantities of potassium magnesium phosphates sulphates and proteins. Hemorrhagic fluid is cloudy with low viscosity and red brown or xanthochromic. Human body is consist of many different types of fluids.
Analysis of Body Fluids in Clinical Chemistry. In this lesson well focus on four body fluids. Some of these fluids are accessible like tears.
The Normal values given below are just for Knowledge purpose and do not consider as an only truthful source of information as Every Laboratory have their own reference ranges as. It is a thick fluid which makes up 55 of the. Non-inflammatory fluid is more than 35 mL volume highly viscous clear and yellow.
In this article we review the published data to evaluate the clinical utility of testing. Electrolyte concentrations of body fluids are usually expressed in milliequivalents per liter mEqL a measure of the number of electrical charges in one liter of solution. Hussong JW and Kjeldsberg CR Eds.
Regulatory agencies only recently began to appreciate the unique nature of each body fluid type and the impact that these variations in chemical composition proteins electrolytes lipids pH etc can have on assay performance. Laboratory testing can be performed on many types of fluids from the body other than blood. In Kjeldsbergs Body Fluid Analysis.
Non-standard body fluids NSBFs can provide essential clinical information otherwise unobtainable with conventional biological specimens. Learn the body fluids chemistry with free interactive flashcards. The laws of chemistry dictate that within a fluid compartment the total number of positive.
Others fluids are harder to obtain like the fluid between your joints. The examples of body fluids are. In a normal adult female is 55 of total body weight is water 39 L.
CSF is normally a clear colorless fluid which circulates around the brain and spinal cord providing a protective cushion for the delicate tissues. Choose from 500 different sets of terms and definitions body fluids chemistry flashcards on Quizlet. 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.
The Asssociation of Clinical Biochemists in Ireland - The Biochemistry of Body Fluids Version 10 October 2009 3 The Asssociation of Clinical Biochemists in Ireland - The Biochemistry of Body Fluids Version 10 October 2009 Diagnostic Use Cerebrospinal fluid can be tested for the diagnosis of a variety of neurological diseases. The main constituents of body fluids are aqueous solutions containing proteins enzymes and salts. The dura mater arachnoid and pia mater Fig.
Inflammatory and septic fluids are cloudy and yellowgreen. Cerebrospinal fluid CSF is the liquid that surrounds the brain and spinal cord. Some body fluid analyses include.
MEqL ion concentration mgL divided by the atomic weight of the ion mgmmol X the number of. Until recently off-label body fluid testing could be performed without as many of the rigorous safeguards that typically apply to other in vitro diagnostics. Blood plasma carries blood cells nutrients hormones and others urine waste product secreted by the kidney interstitial fluid fluid that are located in between cells.
Electrolytes such as sodium bicarbonate and chloride ions. 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. We can compute the concentration of any solution using the following equation.
Among the major applications of body fluid analysis is the differentiation of transudates from exudates for fluids originating from pleural effusions. The brain and spinal cord are covered by the meninges that consist of three layers. This guideline provides guidance to medical laboratories for the appropriate application of measurement procedures for body fluid testing and for reporting results.
1 Given the commonality of pleural effusions presented in the lab clinical distinction between transudate and exudate pleural effusions aids in the diagnosis of the origin of the pleural effusions which in turn affects the. 3 Kjeldsberg CR Grenache DG Couturier MR Cohen MB. The body fluids facilitate the transportation of.
COMPOSITION OF BODY FLUIDS INORGANIC SUBSTANCES. Once a sample is obtained a variety of tests may be performed including chemistry tests microscopic examinations genetic tests and infectious disease tests. These fluids have their own important roles in maintaining the body functions.
This guideline primarily focuses on the recommended. Extracellular fluid contains large quantity of sodium chlorides bicarbonate glucose fatty acids and oxygen. In a normal 154 lb 70 kg adult human male 60 of total body weight ie 42 L is water.
Here is the list of Normal ranges of various Medical Tests. Fetal fibronectin fFN CSF Analysis. Functions of Body Fluids.
To list the general functions and importance of water and electrolytes in the body. Body Fluids Types of Body Fluids. Composition of Body Fluids.
