A sickle cell blood test detects the presence of abnormal hemoglobin S, characteristic of sickle cell disease, a genetic disorder affecting red blood cells.
Sickle cell disease (SCD), also known as sickle cell anemia, is a genetic disorder that affects the red blood cells in the body. It is an inherited condition caused by a mutation in the HBB gene, which encodes a protein called hemoglobin. Hemoglobin is responsible for carrying oxygen from the lungs to the body's tissues. In individuals with sickle cell disease, a specific mutation causes the hemoglobin to form abnormal, rigid, and crescent-shaped red blood cells instead of the normal, flexible, round ones. These abnormal red blood cells are less efficient at carrying oxygen, and they can easily become stuck in small blood vessels, leading to a range of health problems. Treatment for sickle cell disease focuses on managing symptoms and preventing complications. This may include pain management, blood transfusions, medication (such as hydroxyurea), and, in severe cases, bone marrow or stem cell transplantation. Early diagnosis and regular medical care are crucial for individuals with SCD to lead healthier lives and manage their condition effectively.
Key Details
Who Is This For?
Anyone wanting to check specific health markers. People monitoring known conditions or treatment effectiveness. Those who want targeted testing rather than a comprehensive panel. Individuals following up on previous abnormal results or investigating specific symptoms.
What's Included
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
Biomarkers Tested
19Measures the total number of white blood cells, your body's primary defense against infection. Elevated levels may indicate infection, inflammation, or immune disorders, while low levels can signal bone marrow problems or autoimmune conditions.
Measures the number of red blood cells in your blood. Red blood cells carry oxygen from your lungs to every cell in your body. Abnormal levels can indicate anemia, dehydration, or bone marrow disorders.
The iron-rich protein in red blood cells responsible for carrying oxygen throughout your body and returning carbon dioxide to the lungs. Low haemoglobin is the primary marker for anemia and can cause fatigue, weakness, and shortness of breath.
The average size of your red blood cells. Small cells (microcytic) suggest iron deficiency, while large cells (macrocytic) may indicate vitamin B12 or folate deficiency. Normal-sized cells with low count suggest chronic disease.
The average amount of hemoglobin in each red blood cell. Low MCH indicates that red blood cells carry less oxygen than normal, commonly seen in iron-deficiency anemia.
Measures the variation in size among your red blood cells. A high RDW means your red blood cells vary significantly in size, which can help distinguish between different types of anemia.
Imbalances in gut pH influence short-chain fatty acid production and their effects.
Measures monocytes, large white blood cells that mature into macrophages. They play a crucial role in the immune response by engulfing pathogens, dead cells, and debris.
Imbalances in gut pH influence short-chain fatty acid production and their effects.
Imbalances in gut pH influence short-chain fatty acid production and their effects.
Imbalances in gut pH influence short-chain fatty acid production and their effects.
A qualitative test to detect the presence of sickle hemoglobin.
The percentage of your blood volume occupied by red blood cells. It reflects the balance between red blood cell production and loss, helping diagnose anemia, dehydration, and polycythemia.
The average concentration of hemoglobin within each red blood cell. It helps differentiate types of anemia — low MCHC points to iron deficiency, while high MCHC can indicate spherocytosis.
Measures the number of platelets, small cell fragments essential for blood clotting. Low platelets increase bleeding risk, while high platelets may increase clot risk. Important for monitoring clotting disorders and medication effects.
Measures the number of lymphocytes, including B cells and T cells that drive adaptive immunity. Elevated levels may indicate viral infections, while low levels can signal immune deficiency or HIV.
The most abundant type of white blood cell, forming the first line of defense against bacterial and fungal infections. Elevated neutrophils typically indicate active infection or inflammation.
Measures eosinophils, white blood cells involved in fighting parasitic infections and mediating allergic responses. Elevated levels are associated with allergies, asthma, parasitic infections, and certain autoimmune conditions.
The rarest type of white blood cell, involved in allergic reactions and inflammatory responses. Basophils release histamine and heparin, contributing to immediate hypersensitivity reactions.
