Electrocardiography (ECG or EKG) is the process of recording the electrical activity of the heart over a period of time using electrodes placed over the skin.
An echocardiogram is an ultrasound or sound wave test of the heart. The sound waves reflect or echo off the heart to create pictures that can be seen on a screen. Water-soluble gel is placed on the transducer that is then placed on the skin of your chest over the area to be studied.
Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels. Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions.
A Doppler ultrasound is a noninvasive test that can be used to estimate the blood flow through your blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can't show blood flow.
Endoscopy is a nonsurgical procedure used to examine a person's digestive tract. Using an endoscope, a flexible tube with a light and camera attached to it, your doctor can view pictures of your digestive tract on a color TV monitor.

Clinical pathology covers a wide range of laboratory functions and is
concerned with the diagnosis, treatment, and prevention of disease.
Culture and sensitivity in microbiology refers to laboratory techniques
that allow a disease-causing microorganism to be identified.
these fluids are tested instead of blood because they can give more direct answers
to what may be going on in a particular part of the body..
histopathology and cytopathology have been the main
tools utilised in the diagnosis of cancer.
