CHAPTER 3






        WHAT ARE DIAGNOSTIC TESTS?
                iagnostic tests are used by doctors in order to better assess your health situation.
               These tests can be used to help establish your initial diagnosis, assess the
        Deffectiveness of the treatment you are receiving and/or detect potential
        complications. Some tests are simple, so simple that often you are unaware that they
        are happening, like a dipstick analysis of a urine sample. Other diagnostic tests are
        obvious enough for you to be aware of – like having your blood pressure, temperature        DIAGNOSTIC TESTING
        and pulse checked. Another group of diagnostic tests considered to be low-risk and
        non-invasive include x-rays or ultrasound scans.
           As soon as the requirements of a specific test involves entry of a needle or a probe
        into your body, they are considered to be ‘invasive’. These tests include procedures such
        as blood tests, kidney biopsy or x-rays that require an injection of a dye.


        WHY ARE DIAGNOSTIC TESTS IMPORTANT?
           Diagnostic tests are often an important part of establishing what your health problem
        is in order that your doctor and nurse can deliver the treatment and care that will best
        suit your health care needs. The doctor can use other assessment skills to assist in this
        problem-solving process. These skills involve drawing conclusions from a person’s
        medical history and performing a physical examination. However, a diagnostic test is
        often required to establish a diagnosis, to plan an intervention, or to monitor progress.


        URINE TESTS
        What does a dipstick urine test show?
           A dipstick urine test, also known as a urinalysis, is a very simple test that is commonly done in clinics
        or when admitted to the hospital. You will be supplied with a sterile container and asked to carefully pass
        urine into the container to avoid the sample being contaminated. A nurse will insert, into the urine sample,
        a special strip that can detect protein, blood, white blood cells and glucose, in the urine, according to the
        changing colour of the strip.
                                                                                              Dipstick urine test
           Protein – this is an important building block
        in the body. When your kidneys are damaged,
        protein leaks into your urine (proteinuria).
        Persistent protein in the urine suggests
        damage to your kidneys.
           Blood  – The sample will be examined for
        colour and clearness. If blood is present, the
        urine may look red or the colour of cola. This may
        indicate an infection.
           White Blood Cells – Presence in urine
        indicates infection.
           Glucose (sugar) – Presence in urine may
        indicate diabetes.
