Recent studies have found that people who use the blood-thinning drug Xarelto (generic: rivaroxaban) may be unknowingly increasing their risk of developing blood clots and other serious side effects. Concerns have been raised regarding the safety data Bayer provided to the FDA and other regulators about the drug prior to its approval. This article discusses how Xarelto blood clots can be diagnosed.

How are Blood Clots Diagnosed?
The first step in diagnosing a blood clot is to obtain a thorough patient history. If a blood clot is suspected, the history may be expanded to identify potential risk factors or situations that might put the patient at risk for the development of a clot.
- Venous Thrombi – Can cause swelling of an extremity which may be red, warm and tender to the touch. The appearance of these types of clots may be difficult to distinguish from cellulitis or an infection. If there is concern about pulmonary embolism, the doctor may listen to the lungs with a stethoscope to detect abnormal sounds caused by inflamed lung tissue.
- Arterial Thrombus – Symptoms tend to be far more dramatic than those caused by venous thrombi. If a leg or arm is affected, the tissue around the clot may appear white due to a lack of blood supply. Skin may be cool to the touch and there may be loss of sensation and/or movement.
Testing for Venous Blood Clots
Venous clots may be diagnosed several different ways, though ultrasound is the most commonly used method. In cases where an ultrasound is unable to provide a definitive answer, a venography may be performed to detect the clot. In this test, a radioactive dye is injected into a vein in the hand or foot which is monitored via video x-ray as it travels to the heart. The area around a blood clot can thus be visualized.
Blood tests can also be used to diagnose blood clots. “D-Dimer” is produced when blood clots break down, and its levels in the blood can be measured. This is used as a screening test with hopes that the result will be negative so there is no need to look for additional blood clots.
Should a blood clot become trapped in the lungs and cause a life-threatening pulmonary embolism (PE), there are a number of tests that can be used to diagnose the condition. A chest X-ray will not pick up the presence of blood clots, but it may be performed to look for other conditions that cause chest pain and/or shortness of breath, which are the symptoms of a PE. An electrocardiogram may reveal abnormalities characteristic of a pulmonary embolism, and also may reveal other causes of chest pain.
Arterial Clot Tests
Arterial thrombosis is a serious medical emergency, since tissues cannot survive without oxygenated (red) blood for more than a few minutes without sustaining irreversible damage. When this type of clot occurs in an arm or leg, an arteriography may be ordered, a test in which contrast materials are injected into the artery to look for blockage. In cases where a large artery is occluded, arteriographies are performed in the operating room with the presumption that surgery will be needed to open the vessel and restore blood flow.
