A critical role for health professionals is providing support to patients who have entered the health system and who require blood tests and investigations. This chapter provides a guide for the practitioner on blood tests and commonly used investigations and gives an overview of the principles and issues related to these individual tests and investigations. This includes offering simple principles that should be considered when reviewing blood tests; monitoring drug therapies, potential side effects, and risks related to treatment; and further management as and when required. Infections, cardiovascular and respiratory systems, and the possible issues/presenting features related to those prescribed drug therapies are discussed. Radiological investigations, autoimmune profiles, and diagnostic tests such as anti-cyclic citrullinated peptide are also described. An additional critically important aspect is that of tuberculosis issues, therefore the management, screening, and treatment for tuberculosis are also covered.
