Modern Medical Diagnostics and Therapeutic Innovations
Non-Invasive Diagnostic Techniques
Non-invasive techniques are crucial for diagnosing various conditions without requiring surgical entry into the body. These methods provide detailed insights into internal structures and functions, aiding in early detection and treatment planning.
X-ray Imaging
An X-ray is an image registered on a photographic plate of an object exposed to X-rays. This fundamental diagnostic tool is widely used for examining bones, teeth, and certain soft tissues.
Ultrasound Imaging

Direct Blood Pressure Measurement
This method involves inserting a tube or catheter directly into the blood vessel. The catheter is connected to a blood pressure transducer, which generates a corresponding electrical signal. This method is classified into two types:
- Extra-vascular pressure sensor
- Intra-vascular pressure sensor
Indirect Blood Pressure Measurement
In this method, external pressure is applied to the artery using an instrument called a sphygmomanometer. There are two main techniques:
- Palpatory
Medical Diagnostic Tests: ECG, Glucometer, MRI, EEG, X-Rays, PET, Ultrasound
Electrocardiogram (ECG)
An electrocardiogram is a painless test that records the electrical activity of the heart. You will be asked to lie down while a healthcare provider attaches small electrodes to your chest. These electrodes are connected by wires to a machine that turns the heart’s electrical signals into wavy lines, which are printed on paper.
These signals show three parameters: P wave, QRS complex, and ST segment. The size of these parameters and the distance between them can reflect:

Blood Tests: Methods, Analysis, and Safety
Tests on Blood Cells
Blood tests commonly analyze:
- Red blood cells (RBC): 4.5-5.5 million
- White blood cells (WBC): 6,000-10,000
- Blood platelets: 200,000-800,000
Centrifugal Method
By spinning blood in a centrifuge, blood cells sediment at the bottom of the test tube. Most of this column consists of red blood cells, with other cells forming a thin, buffy layer on top. The volume of packed red cells is expressed as a percentage of the total blood volume.
Conductivity (Coulter) Method
This method uses the
