The %LET statement is very often the first macro language statement that is learned. It is roughly the macro language. equivalent of the of the DATA step's assignment statement. One of the easiest ways to define a macro variable is through the %LET statement. (Macro language statements always start. with a %).
Hemolyzed blood is suggestive of renal sources of blood, while non-hemolyzed suggests urinary tract bleeding. Some say Nephrologic vs Urologic causes of blood in the urine. the strip is really a screening tool though and either way blood shows up-a follow up evaluation is needed.Haemolysis is the breaking down of red blood cells.ome say Nephrologic vs Urologic causes of blood in the urine. the strip is really a screening tool though and either way blood shows up-a follow up evaluation is needed.

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.amples with slight hemolysis are analyzed and the results reported with a comment indicating the degree of hemolysis and the effect on the test result. Grossly hemolyzed samples can affect the results of many tests; therefore, a recollection will be requested for most grossly hemolyzed samples.
