Female Weight Control Blood Test — Why It Matters
Managing your weight isn’t just about healthy eating and exercise — your internal health plays a critical role too. A Female Weight Control Blood Test is specifically designed to uncover hidden biological factors that can make it harder (or easier) for women to lose, maintain, or gain weight. It offers a detailed look at the hormones, metabolic markers, and key nutrients that directly influence how your body regulates fat storage, appetite, energy levels, and muscle mass.
This comprehensive blood test focuses on several important areas.
Firstly, it assesses thyroid function by measuring markers like TSH (Thyroid Stimulating Hormone), T3, and T4. Your thyroid acts as the body’s metabolic engine, and when it’s underactive (hypothyroidism), it can significantly slow down metabolism — making weight loss a real struggle even with good habits.
The test also evaluates blood sugar and insulin levels. Insulin is vital for controlling blood sugar, and imbalances can lead to insulin resistance — a condition that encourages fat storage and increases cravings, particularly for sugary foods. Left unaddressed, it can also raise your risk for type 2 diabetes.
Hormonal balance is another major focus. Hormones such as estrogen, testosterone, and cortisol are carefully measured because even small shifts can impact fat distribution, muscle tone, appetite, and energy levels. For instance, elevated cortisol (the stress hormone) is linked to abdominal fat gain, while low estrogen levels, especially after menopause, can slow metabolism and lead to increased fat accumulation.
Lastly, the test checks important vitamin and mineral levels, including Vitamin D, Vitamin B12, Vitamin B9 (Folate), and Ferritin (iron stores). Deficiencies in these nutrients can sap your energy, lower your metabolic rate, and make it even harder to manage your weight effectively.
By understanding these internal factors, you can create a more personalized, targeted plan to help you reach your weight and wellness goals — and finally start seeing the results you deserve.

This blood test is to check on:
- Thyroid function
- Kidney Health
- Liver Health

For best results (if medically suitable) it is advisable to fast (water is allowed) 12 hours prior to the test.
Collection method: Venous blood
Results available: 1-2 days after the sample has reached the laboratory.
Free Thyroxine (Free T4)
This test will measure the amount of free thyroxine in your blood, it will measure how well your thyroid gland is working. T4 is one of the major thyroid hormones in your blood. If the results are too high or too low it can indicate thyroid disease.
Free T3 (FT3)
This test measures the level of triiodothyronine (T3) in your blood. T3 along with T4 are the two major thyroid hormones in your blood. T3 blood test may be used to diagnose hyperthyroidism. If the results are too high or too low it can indicate thyroid disease.
Thyroid Stimulating Hormone (TSH)
This test will measure how much TSH is in your blood.TSH is made in your pituitary, (a gland in your brain) when your thyroid levels are low the pituitary gland makes more TSH and when the thyroid levels are high your pituitary makes less TSH This result indicates how well the thyroid is working.
Bilirubin
Bilirubin is the end product of the breakdown of red blood cells (haemoglobin) It is produced in bone marrow cells and the liver. Bilirubin is a brownish yellow substance and is found in bile which is a fluid in your liver which helps breakdown food. It is excreted through urine and faeces.
The blood test measures the amount of bilirubin in your blood.
Albumin
Albumin, also known as ALB, is a protein made by your liver. Albumin is used to carry hormones, vitamins and enzymes around the body and keep fluid in your
bloodstream to avoid leaking into other tissues.
Globulin
Globulins are a serum protein needed for our growth and development and overall health.
They are produced in the liver and immune system. Different proteins make up the globulin family and many bind with haemoglobin in the blood. Some are involved in the transportation of metals such as iron, whilst others are part of the immune system to help fight infections.
Alkaline Phosphatase (ALP)
Alkaline Phosphatase known commonly as ALP is an enzyme mainly found in the liver, kidneys, bones and digestive system.
The test measures the ALP in your blood.
Alanine Transaminase (ALT)
Alanine Transaminase, known as ALT, is an enzyme most commonly found in the liver. Damaged liver cells release ALT into the bloodstream.
The test measures the amount of ALT in the blood.
Gamma-Glutamyl Transferase (GGT)
Gamma-glutamyl transferase, commonly known as GGT, is an enzyme found throughout the body, however it is most commonly found in the liver.
The test will measure the amount of GGT in the blood.
Total Protein
Proteins are important building blocks for the health and growth of the body’s cells and tissues.
A total protein test measures the amount of albumin and globulin in your body.
Oestradiol/Estrogen/E2
This test measures the Oestradiol in your blood.
Oestradiol also known as E2 is the main form of estrogen in women of reproductive age. It’s a powerful hormone that plays a key role in regulating the menstrual cycle, supporting fertility, and maintaining overall reproductive health.
Aspartate Aminotransferase (AST)
Aspartate Aminotransferase (AST) is an enzyme found in the liver and other tissues. A blood test measures AST to help detect liver damage or other organ injury.
Creatinine
Creatinine is usually passed out through urine. It is a breakdown of waste products made from the muscles.
A high level may be indicative of a kidney problem, however this does depend on muscle mass. Usually if a high muscle mass the creatinine may be higher. If levels are low it could be due to a low protein diet or reduced muscle mass.
Urea
Urea is usually passed out through urine. It is a waste product from the breakdown of amino acids found in proteins.
Higher than normal levels may be indicative of a kidney problem, low levels may be indicative of dehydration.
Estimated glomerular filtration rate (eGFR)
This test will assess how well your kidneys are working.
Cortisol
A cortisol blood test measures the level of cortisol which is a hormone made by your adrenal glands. A cortisol blood test helps assess your body’s stress response and adrenal health, and can uncover hormone imbalances that affect your overall wellbeing.
Testosterone
Testosterone is the primary sex hormone and anabolic steroid in males. It plays a major role in the reproductive tissues such as the prostate and testes. In women it is produced in the ovaries in small amounts and aids the reproductive system.
HbA1c
HbA1c also known as glycated haemoglobin or glycosylated haemoglobin. This test will measure how well your blood sugar level has been controlled over the past 3 months. The results can be indicative of pre or Type 2 diabetes.
Ferritin
Ferritin is a blood protein which stores iron. A ferritin blood test will show if you have too much or too little iron in your body.
Total Vitamin B12
Vitamin B12 is needed in the production of red blood cells, for brain health and to keep nerves healthy, and aids in the making of DNA.
Low levels may indicate anaemia.
Total Vitamin B9 (Folic Acid)
Total Vitamin B9 (Folic Acid) measures the amount of folic acid in your blood, which is essential for healthy cell growth, DNA production, and preventing anemia.
Vitamin D levels
This test will measure the levels of Vitamin D in your body.
