- Results of Transcranial Doppler Ultrasound. A radiologist reviews the recorded images and other test data for evidence of any abnormality. High blood flow velocity suggests that blood flow is too turbulent or that the blood vessel is too narrow. This finding may indicate a blockage, vasospasm, or an arteriovenous malformation.

Tests to diagnose asthma Peak flow What is it? The peak flow test (Peak Expiratory Flow test or PEF) is a lung function test to measure how fast you can breathe out. You take a full breath in, then blow out as fast as you can into a small, hand-held plastic tube called a peak flow meter. The measurement taken is called your peak flow.

- A Doppler test uses ultrasonic waves to assess the movement of blood through the blood vessels. It is used as a preventative measure for conditions such as stroke. The Doppler test usually used on the major veins and arteries of the legs, arms and neck. It is also used to locate blood clots that, if they break loose, can be fatal. During a Doppler test, a device is held over the skin. This device sends and picks up sound waves. The movement of the blood causes changes in pitch.

Doppler Exam: Leg Arterial A leg arterial exam is a test that looks at the blood circulation in the arteries of your arms or legs to see if there is any blockage. Peripheral Circulation. The function of blood circulation is transportation – bringing food and oxygen to the body’s cells and organs.

Doppler ultrasound: What is it used for? Answers from Sheldon G. Sheps, M.D. A Doppler ultrasound is a noninvasive test that can be used to estimate the blood flow through your blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can't show blood flow. A Doppler ultrasound may help diagnose many conditions, including: Blood clots. Poorly functioning valves in your leg veins, which can cause blood or other fluids to pool in your legs (venous insufficiency)

Vascular Lab The Vascular Lab provides non-invasive diagnostic ultrasound tests on arteries and veins, which our doctors use to confirm a diagnosis and determine a course of treatment. These tests may also be used to track disease progression over time. There are generally two kinds of arterial vascular disease: occlusive and aneurysmal.

Doppler Exam: Venous A venous Doppler ultrasound is a diagnostic test used to check the circulation in the large veins in the legs (or sometimes the arms). This exam shows any blockage in the veins by a blood clot or “thrombus” formation. Normal Circulation. The veins return blood to the heart.

Doppler Ultrasound Exam of Arm or Leg Doppler ultrasound is a technique used to measure the flow of blood through your arteries and blood vessels—usually those in your extremities. Vascular flow studies, also known as blood flow studies, can detect abnormal flow within a blood vessel.

- A peak flow test is a simple test to measure how fast you can blow air out of your lungs in one breath. It involves breathing out as quickly and as hard as you can into a small device called a peak flow meter. The result is compared to what's normal for someone of your age, height and gender.

- Pulse Volume Recording. Pulse volume recording, also known as plethysmography, is a noninvasive test that measures blood flow within the blood vessels, or arteries. Its purpose is to help locate blockages in the arteries. Physicians usually perform pulse volume recording on the legs to help diagnose leg artery disease.

Blood Tests That Help Explain Stroke 1 High cholesterol is a major risk factor for stroke and may indicate that you are at greater risk of having a stroke.  Coagulation tests, including prothrombin time (PT), partial thromboplastin time (PTT), and international normalized ratio (INR), check the speed at which your blood clots.

Urine Flow Test A urine flow test calculates the speed of urine flow over time. It may be used to check how the bladder and sphincter are working. The bladder is part of the urinary tract. It’s a hollow muscular organ that relaxes and expands to store urine.

Was the Bible Simply Written By Men? Therefore, his statement that the Bible was written by men was a religious claim—he was claiming to be God. Many follow this same thought process but fail to realize its implications and problems. You shall have no other gods before Me (Exodus 20:3).

- Your doctor may recommend these tests if he or she thinks you have a disorder or disease related to blood clotting. Blood clotting tests also are used to monitor people who are taking medicines to lower the risk of blood clots. Warfarin and heparin are two examples of such medicines.

Evaluation and Tests - Autonomic Testing The nervous system has three parts: motor, sensory and autonomic. The autonomic system manages all internal functions such as blood pressure, blood flow, and sweating. Autonomic tests are conducted to see if the autonomic nervous system is functioning normally.

Nuclear Stress Test If the test shows that blood flow is normal while you are resting but not normal while you are exercising, then doctors know that your blood flow to your heart is not adequate during times of stress.

Diagnosis You also may need an ultrasound test to see if the valves in your veins are functioning normally or if there's any evidence of a blood clot. In this noninvasive test, a technician runs a small hand-held device (transducer), about the size of a bar of soap, against your skin over the area of your body being examined.

What is a Pulmonary Function Test? 2.2 Forced Vital Capacity (Dynamic) Flow volume loops are perhaps the most recognizable of all pulmonary function tests. The shape of the curves are extremely diagnostic but the very nature of the effort required to reproduce the shape (loop) means that often data is of a poor quality.

Peripheral Arterial Disease (PAD) A Doppler ultrasound looks at blood flow in the major arteries and veins in the limbs. During this test, a handheld device is placed on your body and passed back and forth over the affected area. A computer converts sound waves into a picture of blood flow in the arteries and veins.

Evaluation and Tests - Autonomic Testing To see if a disease is affecting the autonomic nervous system, several tests are done to monitor blood pressure, blood flow, heart rate, skin temperature, and sweating. By measuring these functions, it is possible to discover whether or not the autonomic nervous system is functioning normally.

- intracranial atherosclerosis by looking at the blood flow in your brain. A variety of tests can do this. Some take pictures of your blood vessels using a type of X-ray. With these tests, a doctor can see if the arteries are diseased, narrowed, enlarged, or blocked altogether. Other tests use sound waves to study your blood flow. Each test
