OUTLINE OF CONTENT: This CPD seminar will cover the most commonly used tests to determine pathological abnormalities in the following areas: Haematology, Metabolism, Immunology, and Endocrinology.
Laboratory tests will be discussed with reference to clinical evaluation, to form an integrated and holistic approach to analysis and interpretation. The seminar will focus on blood tests that are routinely used by GPs in the UK and Ireland.
LEARNING OUTCOMES: On successful completion of this CPD seminar, practitioners will be able to:
Critically analyse and interpret a variety of clinical laboratory test results for their patients. • Critically evaluate abnormal, borderline and inconsistent test results in order to identify abnormalities. • Combine the results from orthodox laboratory tests and clinical evaluation to form an integrated and holistic approach to analysis and interpretation. • Integrate laboratory test results with history taking and clinical examinations, in order to formulate a diagnosis and determine the most appropriate approach to treatment.
Laboratory tests are tools which are helpful in evaluating the health status of an individual. Disturbances in the normal relative concentration of various blood constituents can help to diagnose and monitor a wide range of health problems. In addition, practitioners need to be able to explain the purpose of the tests and the significance of the results to their patients.
However, It is not possible to diagnose or treat any disease or problem with blood tests alone. Normal result ranges for a particular test are set so that 95% of “healthy” patients fall within the normal range. Therefore 5% of healthy patients fall outside of the normal range, even when there is no abnormality. Conversely, an individual within the large range of “normal” may well be suffering from a pathological condition, with blood tests falling outside their own normal range.
Other factors which may affect test results include the age and/or sex of the patient, the time or day that the sample was collected, and whether the patient is pregnant. ‘Abnormal’ levels of hormones whose ‘normal’ values vary according to the age and/or sex of the patient, and the time or day that the sample was collected, (such as FSH, LH, oestradiol, progesterone, testosterone and cortisol) are not usually highlighted by laboratories, which often leads GPs and other practitioners to miss abnormal results.
Varying levels of globulin binding may also make certain results less reliable, as they render more or less of a particular substance inactive. Furthermore, there may be altered receptor sensitivity (e.g. oestrogen receptors may be increased following use of oestrogen antagonists).
Finally, laboratory tests are very specific, and it is often the case that the range of tests that have been performed is too narrow to make a proper diagnosis. The term ‘full blood count’ is a common cause of confusion, and while patients will often report that their GP ‘tested for everything’, this is impossible.
Reference values shown here are for information only. For most lab tests, there is no universally applicable reference value. A normal result in one lab may be abnormal in another. Therefore, you must use the range supplied by the laboratory that performed your test to evaluate results
