What we test
Iron deficiency is one of the most common causes of fatigue, particularly in women. These comprehensive iron studies provide a complete picture of your iron status and storage.
Ferritin is responsible for storing iron in your body. Low ferritin indicates iron deficiency, which can cause fatigue even before anemia develops.
This is often the first marker to decrease when iron stores are depleted, making it crucial for early detection of iron deficiency.
Iron helps your body produce red blood cells and carry oxygen throughout your body. Low iron levels can lead to anemia and fatigue.
TIBC measures the amount of iron that can be carried by proteins in your blood. High TIBC often indicates iron deficiency.
Transferrin saturation measures the amount of iron in your blood and how well it is being transported. Low saturation indicates iron deficiency.
UIBC measures the amount of iron that can be bound to transferrin. This helps assess your body's capacity to transport iron.
Thyroid disorders are a common cause of fatigue. An underactive thyroid (hypothyroidism) can make you feel sluggish, tired, and lacking energy.
TSH is produced by the pituitary gland and regulates thyroid hormone production. Elevated TSH typically indicates hypothyroidism (underactive thyroid).
Free T4 measures the active thyroid hormone available to your body's cells. Low levels can cause fatigue, weight gain, and feeling cold.
A comprehensive analysis of your blood cells can reveal anemia, infections, or other conditions causing fatigue. Includes red blood cells, white blood cells, and platelets.
Haematocrit measures the proportion of red blood cells in your blood. Low levels indicate anemia, which can cause fatigue.
Haemoglobin is the protein responsible for carrying oxygen from your lungs to your body. Low haemoglobin (anemia) is a common cause of fatigue.
MCHC measures the concentration of haemoglobin in your red blood cells. This helps identify different types of anemia.
MCH measures the average amount of haemoglobin in each red blood cell. Abnormal levels help diagnose the cause of anemia.
MCV measures the average size of your red blood cells. This helps identify different types of anemia and nutritional deficiencies.
MPV measures the average size of your platelets. Changes can indicate various conditions affecting blood clotting.
Platelets help your blood clot. Abnormal counts can cause bleeding or clotting problems and may contribute to fatigue.
Red Cell Count measures the number of red blood cells in your blood. Low counts indicate anemia and can cause fatigue.
RDW measures the variation in size of your red blood cells. High RDW can indicate various types of anemia or nutritional deficiencies.
White Cell Count measures infection-fighting cells in your blood. Abnormal counts can indicate infections or immune system issues that may cause fatigue.
Vitamin D deficiency is increasingly common and can cause fatigue, muscle weakness, and low mood. This is particularly important during winter months when sun exposure is limited.
The test measures 25-OH Vitamin D, which reflects your vitamin D status over the past few months and is the standard marker for vitamin D deficiency.
