"These findings, while promising, will need to be replicated in studies involving more diverse patient populations," Fonarow said.
The patent for the test is held by the University of California Board of Regents, which stands to gain financially should the test be approved.
Detecting patients with deep vein thrombosis or pulmonary embolism often relies on screening blood tests and imaging tests, he explained. "A D dimer blood test is commonly used to screen patients, but has limitations in terms of accuracy," he said.
the test. Sensitivity measures how effective the test is in identifying patients who actually have the condition, and specificity measures the test's ability to identify patients who don't.
The findings were to be presented Sunday at the American Thoracic Society annual meeting in San Diego. Research presented at meetings has not been peer reviewed and should be considered preliminary.
When they tested the urine for concentrations of FPB, researchers found the results were as sensitive as the D dimer blood test, but were more specific.
For the study, Fernandes and colleagues tested stored urine from 344 patients who took part in the Pulmonary Embolism Diagnosis Study.
One expert noted that a better test for spotting clots in the lungs would be a significant advance.

The clot typically forms in the leg, where it is called a deep vein thrombosis, but it can break loose and travel to an artery in the lungs. Once lodged there, the clot, now called a pulmonary embolism, can be life threatening, the researchers noted.
"Pulmonary embolism can be fatal, and accurate detection is critical," said Dr. Gregg Fonarow, director of the Ahmanson UCLA Cardiomyopathy Center, co director of the UCLA Preventative Cardiology Program and associate chief of the UCLA Division of Cardiology.
The new test is not only noninvasive, it is more accurate than the D dimer test, the researchers said.

The urine test can also track ongoing clot activity, another advantage over the D dimer test, which finds a clot only once it begins to dissolve, Fernandes said.
"This would be a tremendous boon to patients from the emergency department to the intensive care unit and even to outpatients," he added.
"Our next steps are to further improve the diagnostic accuracy and performance of the test," Fernandes said. "We plan on evaluating urine FPB in other clinical settings where D dimer has gained traction, such as for determining risk of venous thromboembolism recurrence Nike Air Huarache Nz after anti clotting therapy has been stopped."
The test measures the levels of fibrinopeptide B (FPB), which is released when a clot forms.

Currently, doctors use a blood test to detect these clots. That test looks for a piece of a protein called D dimer, which appears in the blood as a clot starts breaking apart.
