What details are usually looked at when a blood sample is taken? Blood tests are used to check various parts of health through clear and structured numbers. They allow a person to follow any changes over time with simple, repeated checks. While choosing to book a test, you should also compare the blood test price in Dubai to plan better.
Red blood cells (RBCs):
Red blood cells are responsible for carrying oxygen throughout the body. A blood test measures the number of RBCs in the blood, which can indicate conditions such as anemia, dehydration, or blood loss. Low levels of RBCs may suggest anemia, while high levels could indicate dehydration or other underlying issues.
White blood cells (WBCs):
White blood cells are a key part of the immune system. Blood tests measure the count of WBCs to assess the body’s ability to fight infections. A high WBC count might signal an infection, while a low count could suggest a weakened immune system or other health concerns like autoimmune disorders or bone marrow problems.
Platelets:
Platelets help in blood clotting and wound healing. A blood test tracks platelet levels to evaluate how well the blood is clotting. Abnormal platelet counts can point to bleeding disorders, clotting problems, or even certain cancers. High platelet counts may indicate conditions such as inflammation or infection, while low counts might suggest a risk for excessive bleeding.
Blood sugar levels:
Blood tests measure glucose (sugar) levels in the blood, which are key for energy. Abnormal blood sugar levels are a common indicator of conditions such as diabetes or prediabetes. High levels could suggest diabetes, while low levels may indicate hypoglycemia. Regular monitoring helps in managing these conditions and ensuring blood sugar levels remain balanced.
Cholesterol levels:
Cholesterol is a type of fat found in the blood, and its levels can significantly affect heart health. Blood tests typically measure total cholesterol, as well as the levels of LDL (low-density lipoprotein, or “bad” cholesterol) and HDL (high-density lipoprotein, or “good” cholesterol). High levels of LDL cholesterol can increase the risk of heart disease, while HDL cholesterol helps protect the heart.
Liver function tests:
Liver function tests are a series of blood tests used to assess the health of the liver. They measure enzymes and proteins that the liver produces, such as ALT (alanine aminotransferase) and AST (aspartate aminotransferase). High levels of these enzymes may indicate liver damage, infections like hepatitis, or conditions such as fatty liver disease.
