Private Diagnostic Services at Harley Street
Gogodoc offers private diagnostic services for patients who need blood tests, urine tests, stool tests, ECG testing or referral letters for external imaging such as MRI, CT, X-ray or ultrasound. Our clinicians help identify the appropriate investigation and explain next steps.
MRI / CT
(referral support)We do not perform MRI or CT scans directly in clinic, but our GP can assess your symptoms and provide a scan referral letter or help arrange imaging with an external diagnostic provider.
Blood Tests
Our comprehensive blood testing services help monitor and diagnose a wide range of health conditions, providing critical insights into your overall health.
Ultrasound
(referral support)We can provide an ultrasound referral or help arrange an external ultrasound appointment when clinically appropriate. Ultrasound may be used to investigate soft tissue, abdominal, pelvic or musculoskeletal concerns.
Electrocardiogram
ECGs are vital for assessing the heart's electrical activity, helping to diagnose and monitor heart-related conditions.
X-ray
(referral support)We do not perform X-rays directly in clinic, but we can provide an X-ray referral letter or help arrange imaging with an external provider for suitable bone, chest or other clinical concerns.
Echocardiogram
This test uses ultrasound to create images of the heart, allowing our specialists to evaluate heart function and detect potential issues.
