To take the orally disintegrating tablet (Risperdal M-Tabs): 1  Keep the tablet in its blister pack until you are ready to take it. 2  Use dry hands to remove the tablet and place it in your mouth. 3  Do not swallow the tablet whole.
D-dimer levels can be positive due to: 1  Pregnancy. 2  Liver disease. 3  Recent surgery or trauma. 4  High lipid or triglyceride levels. 5  Heart disease. 6  Being over 80 years old.
The major advantage of the D-dimer test is the excellent NPV in the appropriate clinical setting. However, since the positive predictive value (PPV) of the test is low, positive results cannot be used alone in the diagnosis of DVT/pulmonary embolism.
