A platelet is a small, disk-shaped cell in the blood that help with clotting to stop bleeding. When a blood vessel is injured, platelets quickly gather at the place of the injury, sticking to the damaged area and forming a plug to close the wound. They also release substances that help the clotting process by attracting more platelets. This is crucial for preventing excessive bleeding from injuries and for healing.

Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the rest of the body and brings carbon dioxide back to the lungs to be exhaled. It is what makes blood red and is essential for transporting oxygen to tissues and organs. Each hemoglobin molecule can carry up to four oxygen molecules, helping to ensure that the body's cells receive the oxygen they need to function properly.

Hematocrit is the measurement that shows what proportion of blood is made up of red blood cells. It is shown as a percentage, representing how much of the total blood volume is made up of red blood cells. For example, if the hematocrit level is 45%, this means that 45% of the blood's volume is red blood cells, with the rest being plasma and other components. This test helps evaluate overall blood health and can be useful in diagnosing conditions like anemia or polycythemia.

Doppler ultrasound is a medical imaging technique that uses sound waves to evaluate blood flow in the body. During the procedure, a special device called a transducer sends sound waves that bounce off moving blood cells. These reflected waves are then analyzed to measure the speed and direction of blood flow. Doppler ultrasound can help identify issues like blockages, blood clots, or abnormal blood flow patterns in various blood vessels, including those in the heart, neck, and legs. It is commonly used to evaluate the health of the heart and blood vessels and diagnose related conditions.

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.

An anion gap is a blood test measurement used to help identify the cause of an imbalance in the body's acid-base levels. It calculates the difference between positive and negative particles in the blood. Positive particles include sodium, while negative particles include chloride and bicarbonate. Bicarbonate is a substance that helps prevent the blood from becoming too acidic. A normal anion gap helps doctors understand if the acid-base imbalance is due to an increase in acids or a loss of bicarbonate.

A platelet count is a blood test that measures the number of platelets, which are small cells in the blood that help with clotting. Platelets are crucial for stopping bleeding by sticking to injured blood vessels and forming clots. A normal platelet count helps doctors evaluate if a person's blood is clotting properly or if there are issues like bleeding disorders or bone marrow problems. Low or high platelet counts can be sign of various health conditions, such as anemia or infections.

A red blood cell count (RBC count) is a blood test that measures the number of red blood cells in a blood sample. Red blood cells carry oxygen from the lungs to the rest of the body and return carbon dioxide to the lungs to be exhaled. This test helps evaluate overall health and diagnose conditions such as anemia, which is a lack of red blood cells, or other blood disorders. A low level can be a sign of anemia or blood loss, while a high level might suggest conditions such as polycythemia or dehydration.

A reticulocyte count is a blood test that measures the number of reticulocytes, which are immature red blood cells, in a blood sample. Reticulocytes are produced by the bone marrow and are released into the bloodstream before maturing into fully functional red blood cells. This test helps evaluate how well the bone marrow is producing red blood cells and is used to diagnose and monitor conditions such as anemia, blood loss, or bone marrow disorders. An increased reticulocyte count may be a sign that the body is producing more red blood cells to make up for a shortage, while a low count can suggest issues with red blood cell production.

The Red Cell Distribution Width blood test (RDW blood test) measures the difference in size of red blood cells in a blood sample. This test helps evaluate the overall health of red blood cells and can be used to diagnose and monitor different types of anemia and other blood disorders. A high RDW suggests that the red blood cells are very different in size, which may be a sign of anemia or other conditions. A normal RDW means that the red blood cells are similar in size. And a low RDW, may be a sign that the red blood cells are unusually similar in size, which can be seen in certain types of anemia or other health conditions.

A mean platelet volume test (MVP test) measures the average size of platelets in a blood sample. Platelets are small cells in the blood that help with clotting. This test helps evaluate platelet production and function. A high MPV may be a sign that the bone marrow is producing larger, younger platelets, which can occur in conditions like inflammation or certain types of anemia. A low MPV might suggest that platelets are smaller and possibly less effective, which can be seen in some blood disorders. The MPV test is often used alongside other tests to understand platelet health and diagnose related conditions.

Newborn screening is a set of tests performed on infants shortly after birth to check for certain serious health conditions that may not be obvious at birth. These tests typically involve taking a small blood sample from the baby's heel, which is then tested for various conditions such as metabolic disorders, genetic conditions, and other diseases that can be treated early. Early identification through newborn screening allows for immediate treatment and action, which can prevent serious health issues or developmental problems later on.

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.
