What Can a Private Blood Test Detect?

What Can a Private Blood Test Detect? at The Kingston Pharmacy, Kingston upon Thames

How private blood testing can help assess nutritional status, hormone health, organ function, blood health and common causes of unexplained symptoms.

Why Have a Private Blood Test?

Blood tests are one of the most effective ways to assess what is happening inside the body.


Many health conditions develop gradually and may not cause obvious symptoms in their early stages. In other cases, symptoms such as fatigue, hair loss or poor concentration can have many possible causes.


A blood test provides objective information that can help investigate common underlying factors and, where necessary, guide further medical assessment.


Many people also choose private blood testing because they want reassurance about their health or wish to monitor specific aspects of their wellbeing.

What Can a Blood Test Detect?

Depending on the blood test you choose, private testing may provide information about many different areas of your health.

Nutritional and hormonal health

  • Vitamin and mineral levels
  • Iron status
  • Thyroid function
  • Hormone balance
  • Blood health
Organ and general health

  • Liver function
  • Kidney function
  • Cholesterol levels
  • Diabetes risk
  • Inflammation markers
  • General health

Different blood tests are designed for different purposes, which is why choosing the most appropriate profile for your symptoms or health goals is important.

Vitamin and Nutritional Deficiencies

Nutritional deficiencies are common and can sometimes develop without obvious symptoms.

Blood testing may assess nutrients such as

  • Vitamin D
  • Vitamin B12
  • Folate
  • Iron
  • Ferritin
  • Zinc
Fatigue
Brain fog
Hair thinning
Poor concentration
Muscle aches
Reduced wellbeing

Identifying a deficiency allows appropriate treatment or dietary advice where necessary.

Hormone Health

Hormones regulate many important functions throughout the body, including metabolism, energy levels, mood and reproductive health.

Hormone testing may include

  • Testosterone
  • Free Testosterone
  • Oestradiol
  • Luteinising Hormone (LH)
  • Follicle Stimulating Hormone (FSH)
  • Prolactin
  • DHEA-S
  • Sex Hormone Binding Globulin (SHBG)
  • Cortisol
Hormone testing may help investigate

  • Hair loss
  • Low energy
  • Reduced libido
  • Menopause symptoms
  • General hormonal wellbeing

Thyroid Function

The thyroid gland helps regulate metabolism and energy production.


Changes in thyroid function may contribute to a range of symptoms.

Possible symptoms

  • Persistent tiredness
  • Weight changes
  • Hair thinning
  • Feeling unusually cold
  • Brain fog
  • Low mood
Common thyroid markers

  • Thyroid Stimulating Hormone (TSH)
  • Free T4

These markers can provide valuable information about how your thyroid is functioning.

Iron Levels and Anaemia

Iron deficiency is one of the most common nutritional deficiencies and may contribute to several symptoms.

Fatigue
Weakness
Breathlessness
Poor concentration
Reduced exercise tolerance

Iron status may be assessed using

  • Iron
  • Ferritin
  • Transferrin Saturation
  • Total Iron Binding Capacity (TIBC)

Combined with a Full Blood Count, these tests can also help assess for anaemia and provide an overview of your blood health.

Liver and Kidney Function

Your liver and kidneys perform essential roles in filtering waste products, processing nutrients and maintaining normal body function.

Liver function markers

  • ALT
  • AST
  • GGT
  • Bilirubin
Kidney function markers

  • Creatinine
  • eGFR
  • Urea

These tests help provide a broader picture of your overall health and may identify changes that require further assessment.

Cholesterol and Cardiovascular Health

Some of our health screening profiles also assess cholesterol levels and other markers associated with cardiovascular health.


Understanding your cholesterol levels can help you make informed decisions about lifestyle and, where appropriate, discuss further management with a healthcare professional.

General Health Screening

Comprehensive health screening profiles bring together multiple blood tests to provide a broad overview of your health.

Depending on the package selected, testing may include

  • Blood health
  • Organ function
  • Hormone levels
  • Vitamin status

  • Thyroid function
  • Cardiovascular health
  • Diabetes risk

These profiles are suitable for people who want a proactive assessment of their health or who have symptoms that may require further investigation.
