Blood Test

Blood type refers to the classification of blood based on certain substances found on red blood cells. The main blood types are A, B, AB, and O, depending on which substances are present or missing. Blood can also be either Rh-positive or Rh-negative, which means it has or does not have an additional substance called the Rh factor. Knowing a person’s blood type is crucial for safe blood donations and organ replacements, as matching the blood types helps avoid dangerous reactions.

Angiography is a medical imaging technique used to view the inside of blood vessels and organs. During the procedure, a special dye is injected into the blood vessels to make them visible on X-ray images. This dye helps make any blockages, narrowing, or other issues in the blood vessels visible. Angiography is commonly used to examine the heart, brain, and other parts of the body to diagnose and plan treatments for conditions related to blood vessels.

Erythrocyte sedimentation rate (ESR) is a blood test that measures how quickly red blood cells settle at the bottom of a test tube over a certain amount of time. This settling rate is influenced by the presence of proteins in the blood that increase during inflammation or infection. A faster-than-normal rate may indicate inflammation, infection, or other medical conditions such as arthritis, lupus, or some cancers in the body. This test is often used alongside other tests to help diagnose or monitor these conditions and evaluate the effectiveness of treatments.

A complete blood count (CBC) is a common blood test that measures the levels of different cells in the blood, including red blood cells, white blood cells, and platelets. This test helps evaluate overall health and identify various conditions, such as infections, anemia, and blood disorders. By analyzing the numbers and types of these cells, a CBC provides important information about the body's ability to fight infections, carry oxygen, and clot blood properly.

Blood glucose refers to the amount of sugar, also known as glucose, present in the blood. Glucose is a main source of energy for the body’s cells. Measuring blood glucose levels helps to monitor and manage conditions like diabetes, where the body has trouble controlling blood sugar levels. Blood glucose tests can be performed after not eating for a period of time or at random times, depending on the purpose. Consistently high or low levels can indicate problems with blood sugar control and help doctors in diagnosing and managing diabetes and other related conditions.

Rhesus factor, or Rh factor, is a protein found on the surface of red blood cells that determines whether a person's blood type is Rh-positive or Rh-negative. If the protein is present, the blood type is Rh-positive; if absent, it is Rh-negative. This factor is inherited from one's parents, and knowing one's Rh factor is important for safe blood transfers and during pregnancy, as different Rh factors between mother and baby can lead to complications.
