D-Dimer blood test that is done to look for possible blood clots is most accurate when done by enzyme-linked immunosorbent assays (ELISAs) that had the highest sensitivity and lowest negative likelihood ratio, which makes ELISA the best D-dimer test for excluding blood clots in legs and lungs.

Vitamin C has been shown to kill cancer cell in test tubes. Unfortunately, the Vitamin C taken by mouth does not increase the level of Vitamin C in the blood high enough to have any effect because the body does not absorb vitamin C beyond what it needs. The vitamin C administered intravenously ( IV ) seems to produce levels 70 times greater than if taken by mouth. More research is needed to see if levels this high will help in treatment of cancer.

CRP test may not have as much value as has been reported for predicting risk of heart attack based on a recent study. CRP or C-reactive Protein is a test of inflammation that can increase with heart attack as well as certain types of arthritis and infection. The New England Journal of Medicine

B-type natriuretic peptide levels are higher in patients with congestive heart failure than in patients with shortness of breath from other causes. Therefore measuring this test in patients with shortness of breath can tell you if the cause is from heart failure resulting in early treatment and discharge from hospital.

C-reactive Protein is a test of inflammation that may help in detection of colorectal cancer. Patients with colon cancer were noted to have elevated C-reactive protein test before. This may be a useful test in early detection of colon cancer. The Journal of The American Medical Association
