Hello and welcome to HCM, The interpretation of the stool test is as follows: The physical characters i.e. color, consistency, reaction are all within normal limits. The microscopic examination reveals that ova or cyst are absent thus, confirming that no parasitic infection is present in the gastrointestinal tract. Absence of pus cells rules out bacterial infection. However, presence of red blood cells suggests presence of bleeding at some site of the gastrointestinal tract. Blood is stools is commonly seen in infection, dysentery, or bleeding from some growth or polyp, etc. Since, there is no evidence of infection, red blood cells can be due to some kind of bleeding in the gastrointestinal tract. You need to consult your treating doctor for further investigations to know the cause of bleeding in the gastrointestinal tract. Thanks and take care Dr Shailja P Wahal
