SelectedThe Premier Health Profile is a comprehensive blood test designed to give an in-depth overview of your general health. It assesses key systems including kidney function, liver health, blood cells, iron status, metabolism, electrolytes, and cardiovascular risk.
This profile includes:
Urea & Electrolytes (U&Es)
eGFR
Liver Function Tests (LFTs)
Glucose
Iron (Fe), UIBC, TIBC, Transferrin Saturation
Lactate Dehydrogenase (LDH)
Creatine Kinase (CK)
Calcium & Phosphate
Uric Acid
Cholesterol Profile (Total, HDL, LDL, Triglycerides)
Full Blood Count (FBC)
Erythrocyte Sedimentation Rate (ESR)
Together, these markers provide a detailed snapshot of organ health, nutritional status, inflammation, and metabolic balance.
Many health conditions develop silently before symptoms appear. The Premier Health Profile helps identify early abnormalities across multiple systems, allowing proactive management before problems become more serious.
This test is ideal for routine health screening, ongoing monitoring of chronic conditions, or when symptoms are vague and unexplained.
You may benefit from this test if you experience:
Persistent fatigue or low energy
Unexplained aches or muscle weakness
Weight changes or metabolic concerns
Family history of chronic disease
Cardiovascular risk factors
Monitoring of kidney or liver health
General health optimisation or annual screening
Unexplained inflammation or infection markers
Comprehensive organ health assessment
Evaluates liver, kidney, and metabolic function in one test.
Screens for anaemia and blood disorders
FBC and iron studies assess red and white blood cells.
Assesses electrolyte and mineral balance
Sodium, potassium, calcium, and phosphate support nerve and muscle health.
Evaluates blood sugar control
Glucose supports metabolic and diabetes risk assessment.
Monitors cardiovascular risk
Full cholesterol profile assesses heart disease risk.
Identifies inflammation or infection
ESR and LDH help detect inflammatory processes.
Supports muscle and tissue health assessment
CK and LDH reflect muscle and cellular stress.
Ideal for preventive health screening
Detects early abnormalities before symptoms develop.

Low values may indicate nutritional deficiencies, anaemia, electrolyte imbalance, reduced kidney function, or hormonal or metabolic issues depending on the marker affected.
Symptoms may include fatigue, weakness, dizziness, or poor exercise tolerance.
UK reference interpretation:
Low: Below laboratory reference ranges
Results within range suggest balanced organ function, normal blood counts, stable metabolism, and no significant inflammatory activity at the time of testing.
Normal results support overall health reassurance and baseline monitoring.
UK reference interpretation:
Normal: Within laboratory reference ranges
Elevated values may reflect inflammation, infection, liver stress, kidney dysfunction, muscle breakdown, high cholesterol, or metabolic imbalance depending on the marker.
Further clinical correlation may be advised to determine significance.
UK reference interpretation:
High: Above laboratory reference ranges

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
