Q&A
Helps you know your test better
Q. Will the radiology scan be painful or uncomfortable?
A. Most radiology scans are completely painless. You might need to lie still for a few minutes, but there's no discomfort involved. If contrast dye is used, you may experience a slight pinch during the injection or a warm sensation for a moment; this is normal. So, don't panic; you can undergo the radiology scans as recommended by the doctor without worrying about discomfort. At Redcliffe Labs, all scans are performed carefully under the supervision of our team of expert radiologists, ensuring that all safety protocols are followed and you are in safe hands.
Q. How long will the scan take, and when will I get my report?
A. Usually, most of the radiology scans take between 15 to 30 minutes, depending on the type of scan, the underlying cause, or the scanning site. In most cases, you'll receive your reports within 24 to 48 hours, sometimes even sooner if required urgently.
Q. Can I take my regular medications before the scan?
A. Yes, in most cases you can continue your regular medicines. However, if your scan requires fasting or the use of contrast, your doctor or technician may provide you with specific instructions in advance. It's essential to follow these instructions to ensure the scan is accurate. Consider consulting with the lab technician or the doctor for additional information required before the scan.
Q. Is fasting recommended before the scan?
A. Nope, you don't need to fast for most radiology tests like X-rays, brain scans, or routine MRIs. You can eat and drink as you normally would, unless your doctor gives you specific instructions.
Frequently Asked Questions
An ECG is a simple and painless test that records the electrical activity of your heart, helping doctors assess heart function and detect rhythm or structural abnormalities.
It is done to evaluate symptoms such as chest pain, shortness of breath, dizziness, or palpitations, and to detect heart conditions like arrhythmias, heart attacks, or other cardiac disorders. It is also used in routine check-ups or pre-surgery evaluations.
Electrodes attached to the chest, arms, and legs record the electrical impulses of each heartbeat. Irregularities in the timing, shape, or rhythm of the waves can indicate arrhythmias, ischemia, or structural heart issues.
ECG can detect arrhythmias, myocardial infarction (heart attack), coronary artery disease, enlarged heart chambers, electrolyte imbalances, and the effects of certain medications on the heart.
Small sticky electrodes are placed on the chest, arms, and legs. These electrodes connect to an ECG machine that records the heart's electrical activity. The test is quick, painless, and usually takes a few minutes.
No fasting is required. You can eat and drink normally, but avoid applying lotions or oils on the chest before the test as they can affect electrode contact.
The entire process, including setup, takes 5–10 minutes. The actual recording of the heart’s electrical activity takes less than a minute. Results are usually available immediately.
Resting ECG records heart activity while lying still. Stress ECG (treadmill test) monitors heart response during exercise. Holter monitoring records heart activity continuously over 24–48 hours during daily activities.
ECG is very safe and non-invasive. It does not send current into the body, only records signals. Mild discomfort may occur when removing the adhesive electrodes.
A normal ECG shows a steady rhythm with clearly defined P, QRS, and T waves. Abnormal patterns can indicate irregular rhythms, heart attack damage, or conduction defects, which are interpreted by a cardiologist.
