FAQs
What is a Colour Doppler Test?
A Colour Doppler Test is an advanced ultrasound technique that evaluates blood flow in arteries and veins. By creating detailed images of blood flow speed and direction, the test helps doctors diagnose conditions like blood clots, narrowed or blocked vessels or even impaired circulation. This non-invasive procedure is safe for all ages and painless. It is safe for all age groups and involves using a handheld transducer to capture real-time images of blood flow.
Who should consider a Colour Doppler Test?
A Colour Doppler Test is recommended for people with symptoms like swelling, pain, or numbness in the limbs, as these may indicate blood flow problems. It is useful for diagnosing conditions such as blood clots, blocked or narrowed blood vessels, varicose veins, and poor circulation. Pregnant women may need this test to check blood flow in the placenta and umbilical cord for the baby’s health. It is also suggested for individuals at risk of vascular diseases or those undergoing treatment for heart or circulation problems to monitor progress and guide care.
How is a Colour Doppler Test performed?
A Colour Doppler Test is a non-invasive and painless procedure performed using ultrasound technology. A gel is applied to the area being examined to facilitate the transmission of sound waves. A handheld device called a transducer is then placed on the skin and moved gently over the area. The transducer emits high-frequency sound waves that bounce off blood vessels, creating real-time images on a monitor. These images show the speed, direction, and flow of blood in the arteries and veins. The process typically takes 20–40 minutes and is closely monitored by a trained technician or radiologist to ensure accurate results.
Is the Colour Doppler Test safe?
Absolutely. The Colour Doppler Test is safe and non-invasive. It doesn't use radiation, and you won't experience any side effects. That makes it suitable for people of all ages, including pregnant women and children.
Do I need to prepare for a Colour Doppler Test?
Preparation is usually minimal. For tests involving abdominal blood flow, you may need to fast for 6-8 hours beforehand. For other areas, you can just wear loose, comfortable clothing that allows easy access to the area being tested. Your doctor or the diagnostic centre will give you specific instructions to follow to ensure you get the most accurate results.

What happens if the results are abnormal?
If the results of the Colour Doppler are abnormal, it may indicate blood clots, blocked or narrowed blood vessels, or reduced blood flow to organs. Such findings can be related to conditions like deep vein thrombosis, arterial diseases or varicose veins. In pregnancy, abnormal results may suggest insufficient blood supply to the foetus or problems with the placenta. Your doctor will evaluate these findings and may recommend additional tests like angiography, MRI or CT scan to confirm the diagnosis and extent of the condition. Based on the results, treatment may involve medications to improve blood flow, dissolve clots or manage underlying conditions.
How safe is a Colour Doppler Test during pregnancy?
Colour Doppler is completely safe during pregnancy. It uses ultrasound technology which does not involve radiation making it ideal for monitoring blood flow in the placenta and umbilical cord. This test gives vital information about the foetus health and ensures any potential complications are detected early.
