Skin Cancer Foundation. http://visualsonline.cancer.gov/about.cfm. The ABCDEs of melanoma skin cancer are: 1  Asymmetry. One half doesn't match the appearance of the other half.  Border irregularity. The edges are ragged, notched, or blurred.
Effects of Hemolysis on Clinical Specimens. Hemolysis due to the breakdown of red blood cells is important to the laboratory because it can have an effect on laboratory results. The effects can be the result of products liberated from the red cells themselves, or due to interferences with laboratory analyzers.
In cases where a workup is negative and the cause of the hematuria remains unknown, observation with repeat urinalyses is a reasonable option. A blood test to check kidney function and a blood-pressure check should be done as well.
