When clotting needs checking
How well your blood clots matters for surgery, for medication safety and for getting to the bottom of unexplained bruising. This screen is a sensible first step if you recognise any of these.
On warfarin
Warfarin therapy needs regular INR monitoring to keep the dose safe and effective.
Easy bruising or bleeding
Unexplained bruising, nosebleeds or prolonged bleeding from minor cuts.
Liver disease
The liver makes most clotting factors, so liver problems can prolong clotting.
Before surgery
A baseline clotting check ahead of a planned procedure.
Family history
A family history of bleeding disorders you'd like to investigate.
Medication review
Reassurance and a clear read on your clotting while on anticoagulants.

Understanding your Coagulation Screen results
Each result in your Coagulation Screen is reviewed by a clinician before release. Below is a plain-English guide to the key markers included in this panel.
Key Biomarkers
This panel assesses the key markers relevant to coagulation screen. Each result is reviewed by a clinician who will flag any values outside the expected range for your age and sex.
Reference Ranges
Reference intervals are population-derived and should be interpreted alongside your symptoms and clinical history — a result within range does not always exclude pathology, and a mildly out-of-range result may be clinically insignificant in isolation.
Reference ranges vary between laboratories and are influenced by age, sex, and other individual factors. This information is for educational purposes only and does not replace a clinical consultation. The Vesey reviews every result before it is released to you.
