Question 1

What is the difference between finger-prick and venous blood tests?

Accepted Answer

Finger-prick tests collect small capillary blood samples using a lancet, making them convenient for home use. Venous blood draws take blood directly from a vein in your arm, typically requiring a trained phlebotomist. While finger-prick tests suit many routine biomarkers, some complex assays or sensitive blood counts require the larger sample volume provided by a venous draw to prevent clotting or sample degradation.

Question 2

Can I share private blood test results with my NHS GP?

Accepted Answer

Yes. Most private laboratories supply a downloadable PDF report detailing your biomarkers, numeric values, and standard reference ranges. You can present this document to your NHS GP. However, NHS clinicians will review private findings in the context of your overall clinical history, and they may choose to repeat certain tests within NHS laboratories before initiating treatment.

Question 3

Why do private blood test prices vary across providers?

Accepted Answer

Price differences often reflect whether the test covers a single marker or an extensive panel, the type of laboratory technology used, and the level of medical oversight included. Variations can also stem from whether home postal logistics, clinic phlebotomy appointments, or registered doctor review notes are bundled into the listed cost or charged separately.

Question 4

Are at-home blood test results reliable?

Accepted Answer

Home kits processed by accredited UK laboratories use validated diagnostic equipment. However, sample quality depends heavily on correct collection technique. Inadequate blood volume or squeezing the finger excessively can cause haemolysis (damage to red blood cells), which may invalidate results and necessitate a retest. Carefully following the enclosed instructions helps ensure an adequate sample.

Question 5

What should I do if my test shows an abnormal result?

Accepted Answer

If your private results fall outside normal reference ranges, do not attempt to self-diagnose or alter prescribed medications independently. Download your full laboratory report and schedule a consultation with an NHS GP or private doctor. A clinician will interpret the abnormal biomarker in the context of your symptoms, medical history, and overall lifestyle.

Question 6

Do private tests include doctor interpretation?

Accepted Answer

Inclusions vary by provider and test tier. Many UK home testing services include a brief commentary written by an in-house GMC-registered doctor highlighting abnormal markers. Other standalone or single-marker tests may provide only the raw laboratory figures against standard reference intervals. Always review the product specifications in the comparison below to confirm what commentary is provided.
