Diagnostic blood tests can provide useful information about your health, from checking specific symptoms to monitoring an existing condition. At Murrayfield Pharmacy in Edinburgh, private diagnostic blood testing offers a convenient way to arrange selected tests without waiting for a routine appointment.
A blood test is a clinical investigation rather than a diagnosis in itself. Results need to be considered alongside your symptoms, medical history, medicines, examination findings and, where appropriate, further investigations. Our pharmacy team can explain the testing process and help you understand what your results may indicate. If a result needs medical follow-up, you may be advised to contact your GP or another appropriate healthcare professional.
What is a diagnostic blood test?
A diagnostic blood test analyses a sample of blood for particular substances, cells or markers. Different tests answer different clinical questions. For example, a test may assess how an organ is functioning, identify evidence of inflammation, measure hormone levels or check for nutritional deficiencies.
Some people arrange testing because they have symptoms such as persistent tiredness, changes in weight, dizziness or changes in their general wellbeing. Others may want to monitor a known condition or review a health marker as part of a broader health check.
The most suitable test depends on the reason for testing. A broad panel is not always better than a targeted test, and not every possible cause of a symptom can be identified through blood testing. During the consultation, you may be asked about your symptoms, relevant medical conditions, medicines and the purpose of the test.
How pharmacy blood testing works
1. Booking and clinical assessment
You can arrange a private diagnostic blood test at Murrayfield Pharmacy. Before the sample is taken, the clinical team will confirm which test or tests are required and check that the service is appropriate for you. This is an opportunity to discuss any preparation instructions, including whether you need to avoid food for a specified period.
It is important to provide accurate information about medicines, supplements, pregnancy or possible pregnancy, relevant medical conditions and any recent illness. These factors can affect which tests are suitable and how results are interpreted.
2. Sample collection
A trained healthcare professional will take a blood sample, usually from a vein in your arm. The skin is cleaned first, and a sterile needle is used to collect blood into one or more labelled tubes. The procedure generally takes only a few minutes.
You may feel a brief sharp scratch or pressure during collection. Some people experience temporary bruising, tenderness or light-headedness afterwards. Tell the healthcare professional if you have previously felt faint during a blood test, and remain seated until you feel well enough to leave.
3. Laboratory analysis
Your sample is sent for analysis according to the test requested. Turnaround times vary depending on the type of test and the laboratory processing it. Some results may be available relatively quickly, while more specialised investigations can take longer.
You should follow the instructions provided about when and how your results will be communicated. Results may be supplied through a secure system or discussed with you by an appropriate healthcare professional, depending on the service arranged.
What can blood test results tell you?
The information provided depends on the test performed. Examples of commonly assessed areas include:
-
Blood cells, which can help assess patterns associated with anaemia, infection or other blood-related conditions.
-
Kidney and liver markers, which provide information about aspects of organ function.
-
Cholesterol and other lipid measurements, which may help assess cardiovascular risk alongside factors such as blood pressure, smoking, diabetes and family history.
-
Glucose or longer-term glucose markers, which can help assess blood sugar regulation.
-
Thyroid hormones, which may be relevant when symptoms suggest altered thyroid function.
-
Iron, vitamin or other nutritional markers, when deficiency or excess is a clinical consideration.
-
Inflammatory or immune markers, where these are appropriate to the symptoms and clinical question.
A result outside the laboratory’s reference range does not automatically mean that you have a disease. Healthy people can occasionally have results just outside a reference range, and a result within the range does not always exclude a health problem. Reference ranges may vary between laboratories and can be influenced by age, sex, pregnancy, timing, fasting status, hydration, recent exercise and medicines.
Understanding your results
Results are usually reported with a reference range. This is a range of values seen in a defined population and is used as a guide when interpreting an individual result. It is not the same as a guarantee that every value within the range is healthy for every person.
It is often more useful to consider patterns across several results than to focus on one isolated number. For example, a mildly altered result may need to be repeated, compared with previous tests or interpreted alongside other markers. If you are taking supplements or medicines that may affect a result, do not stop them unless advised by a qualified healthcare professional.
Where a result is unexpected, the next step may be further testing, clinical monitoring or a discussion with your GP. Murrayfield Pharmacy can help explain the report, but private pharmacy testing does not replace NHS care or a GP assessment when one is needed.
Preparing for your blood test
Preparation depends on the test. You may be asked to fast, take the sample at a particular time of day or avoid strenuous exercise beforehand. Not all blood tests require fasting, so do not fast unless you have been specifically instructed to do so.
-
Drink water unless you have been told otherwise. Being well hydrated can make blood collection easier.
-
Bring details of your medicines and supplements, including non-prescription products.
-
Tell the clinician if you are pregnant, may be pregnant or have a condition that affects blood clotting.
-
Wear clothing that allows easy access to your arm.
-
Let the team know if you feel unwell or have a history of fainting with needles.
When to seek medical advice
A private blood test should not delay urgent medical care. If you have severe chest pain, significant breathing difficulty, sudden weakness, confusion, heavy bleeding or another serious or rapidly worsening symptom, seek urgent help through NHS 111 or emergency services as appropriate.
If your results suggest a potentially important abnormality, you may be advised to contact your GP promptly. The pharmacy team can explain the result and recommend appropriate follow-up, but only a suitable clinician with access to your full medical history can determine the next stage of care.
