An example of the indispensability of a coordinated procedure is stool samples for instance. The pathogens sought for do not always occur homogeneously (i.e. evenly distributed). If this is not taken into account or if errors are made in the extraction and submission of the material, false-negative findings may occur.
Unfortunately, a negative result is often quickly derived from one or two negative specimens – which would perhaps be positive, if the specimens were collected in a controlled manner or if a further and correct investigative examinations were carried out. Within the framework of Normamed quality assurance, this circumstance is taken into account with a chain of measures to increase the quality of the evaluation.
It principally allows the requirement of a certain number of specimens in order to avoid false-negatives. Doing this in a non-specific way has a number of disadvantages in addition to high costs and does not solve other problems that need to be considered (e.g. the overgrowth of pathogenic yeasts with food yeasts or the fact that not every sample is suitable for evaluation).
It is therefore more important to integrate a plausibility check into the system. Simply put, it means: Given that all relevant factors forming the ailment are taken into account – could this be “right” as a result of the laboratory examination?
This test includes expertise regarding possible pathogens, answers from the anamnesis, information from other examinations and comparisons with similar disease patterns. For this integration, the patient must understand, want and authorise the therapist’s cooperation with the laboratory. Corresponding template management and processing can also be carried out.
The enlightened patient does not expect “abstract”, “dissociated diagnosis”, but rather a solid solution to his health problems by the meaningful execution of necessary and suitable laboratory analysis.
Many specimen (e.g. mouth swabs, urine, stool) can be taken by patients at their end. Normamed provides patient information for specimen and material collection because proper results and initiation of proper treatment require meticulous care. You can download it here.
