An injection is a method of delivering medication or fluids into the body using a needle and syringe. It can be given into different areas, such as a muscle, vein, or under the skin, depending on the type of medication and its intended effect. Injections are used for vaccines, pain relief, hormones, and other treatments that need to be given directly into the bloodstream or tissues.

An electrocardiogram (ECG or EKG) is a recording that shows the electrical activity of the heart. It is produced during an electrocardiography test, where small sensors called electrodes are placed on the skin of the chest, arms, and legs. These electrodes pick up the heart’s electrical signals and create a visual representation of the heart's rhythm and activity. The ECG recording helps doctors diagnose heart conditions, such as arrhythmias and heart attacks, by revealing any irregularities in the heart’s electrical patterns. The test is quick, does not involve any surgery or needles, and provides valuable information about heart health.

An X-ray is an image created using a type of radiation that passes through the body to produce pictures of the internal structures. During the X-ray procedure, a small amount of radiation is directed at the area being examined, and a device on the other side captures the radiation that passes through, creating a detailed image. X-rays are commonly used to examine bones, detect fractures, and identify issues in organs or tissues. The images help doctors diagnose conditions, monitor progress, and plan treatments.

A blood test is a medical procedure where a small sample of blood is taken from the body to be analyzed in a lab. It helps doctors check for various health conditions, measure how well organs like the liver and kidneys are working, and see if treatments are effective. Blood tests can identify infections, monitor chronic diseases, and check for substances like glucose, cholesterol, and hormones. The sample is usually taken from a vein in the arm using a needle, and the procedure is quick and rather painless.
