The JDJ Diagnostics User Handbook shall provide a comprehensive list of tests currently offered. The majority of tests are performed on site, however a few of the tests may be referred to other accredited contracted service providers.

Chemical Pathology

Chemical pathology (also known as clinical biochemistry) involves the biochemical investigation of bodily fluids such as blood, urine and cerebrospinal fluid. By discovering how and where the body’s chemistry has changed, diseases can be diagnosed and monitored. Tests are designed to detect these changes qualitatively or quantitatively compared to results from healthy people.


Diagnosing diseases by looking at single cells and small clusters of cells is called cytology or cytopathology. It’s an important part of diagnosing some types of cancer. Cytology is the examination of cells from the body under a microscope. In a urine cytology exam, a doctor looks at cells collected from a urine specimen to see how they look and function. The test commonly checks for infection, inflammatory disease of the urinary tract, cancer, or precancerous conditions.


Endocrinology is the field of hormone-related diseases. An endocrinologist can diagnose and treat hormone problems and the complications that arise from them. Hormones regulate metabolism, respiration, growth, reproduction, sensory perception, and movement. Hormone imbalances are the underlying reason for a wide range of medical conditions.


Haematology is the branch of medicine concerned with the study of the cause, prognosis, treatment, and prevention of diseases related to blood. It covers the cellular composition of blood, blood cell formation, haemoglobin synthesis and all related disorders.


Histology is the study of tissues and their structure. The structure of each tissue is directly related to its function, so histology is related to anatomy and physiology.


Immunology deals with physical, chemical and physiological characteristics of the components of the immune system in vitro, in situ, and in vivo.


Microbiology is a field of medicine involved with diagnosing and treating infectious diseases caused by micro-organisms. These include bacteria, mycobacteria, viruses, fungi and parasites.

Molecular Diagnostics

Molecular biology is the study of the molecular building blocks of a patient. It examines the structure, function, and makeup of the various systems of a cell.


Serology is the study of serum and other body fluids, it refers to the diagnostic identification of antibodies in the serum. Sometimes the body mistakes its own healthy tissue for outside invaders and produces unnecessary antibodies. This is known as an autoimmune disorder. Serologic testing can detect these antibodies and help your doctor diagnose an autoimmune disorder.

TB and HIV Viral Load testing

Viral load testing measures the amount of genetic material (RNA) in the blood and reports how many copies of the virus are present.


Virology is the study of viruses – submicroscopic, parasitic particles of genetic material contained in a protein coat – and virus-like agents.
