The copro parasitologie des selles invention belongs to the technical field of quality control methods of detection methods for the presence of microorganisms in the stool. Health facilities include hospitals, clinics, doctors' offices, Medical Biology Laboratories LBM of private and public analysis.

These, as part of their activities, carry out regular analyzes on samples such as blood, urine or feces. The results of these analyzes provide information about a physiological condition, such as pregnancy or disease, such as copro parasitologie des selles, cancer, flu.
These laboratories must be accredited in all copro parasitologie des selles their activity later than 31 October It allows the verification of the quality of analysis thus results, empowerment and qualification of personnel. To be accredited, the Medical Biology Laboratories must meet many requirements.

Validation techniques they use to perform the analyzes, in part. Cette validation des techniques est obtenue par: This validation techniques is achieved by: Products or samples are offered by companies or associations, LBM for blind copro parasitologie des selles to evaluate the quality of services results, ie the correctness and accuracy of the laboratory.
CQI devices are offered in all areas of medical biology. Cependant peu d'entre eux concernent la parasitologie. However few of copro parasitologie des selles relate parasitology. One of the major challenges in this area is the development of products known CQI requires, in some cases, samples of human origin blood, stool containing parasites, such as plasmodium malaria agents or amoebas present in developing countries.
For the diagnosis of intestinal parasites, LBM realize techniques for search and identification of parasites in faeces.

In the nomenclature of copro parasitologie des selles procedures performed in medical laboratories, research parasites in stool includes: The methods used for the concentration of parasites in the feces are classified according to principle: They use a liquid of density lower than parasites that are then found in the sediment or in the pellet - flotation concentration methods.
They use a liquid density greater than parasites that are then found on the surface of the liquid, - methods biphasic concentration or physicochemical. They use an aqueous solution and an immiscible solvent such as ether or ethyl acetate.
In a centrifuge tube, feces are suspended in an aqueous solution. After addition of the solvent and stirring to obtain an emulsion, the tube is centrifuged to break the emulsion and copro parasitologie des selles separation of the elements present in stool, according their hydrophilic-lipophilic balance.
With these methods, a copro parasitologie des selles part of fecal debris localizes in the organic phase or at the interface, and parasites, cysts or eggs, generally hydrophilic are found in the pellet.
Each of these methods is described in the art and well known to those skilled in the art. The CQI for these methods of concentration of parasites in faeces, should copro parasitologie des selles treated as the samples to be analyzed.
They must therefore contain feces or be incorporated into the stool before the completion copro parasitologie des selles the concentration to evaluate technique.
The problem is obtaining parasitized human faeces, as raw material in an amount sufficient for the realization copro parasitologie des selles such a CQI.
Indeed in industrialized countries, intestinal parasites are scarce or nonexistent for some, and in developing countries the recovery, securing and shipping stool, sufficient for the realization of several batches of CQI, are not easy to implement.
