The diagnostic criteria for asymptomatic microhematuria are evaluated by considering two essential conditions related to urine analysis:

- The first condition is the presence of three or more red blood cells per high-power field (RBC/HPF) in a properly collected urinary specimen.
- The second condition involves the exclusion of any obvious benign causes for these red blood cells in the urine.

To determine if the diagnostic criteria are met, both conditions must be affirmatively selected by the user. Here's a breakdown of how the evaluation works:

- For Condition A (Presence of >= 3 RBC/HPF):
  - The user must confirm that the urinary specimen contains three or more red blood cells per high-power field. If this option is selected, Condition A is regarded as true.
  
- For Condition B (Exclusion of obvious benign cause):
  - The user needs to specify that no obvious benign cause accounts for the presence of red blood cells in the urine. If this option is selected, Condition B is considered true.

Both conditions need to be true for the diagnostic criteria to be satisfied. This means that if both the presence of red blood cells and the exclusion of benign causes are confirmed, the criteria for asymptomatic microhematuria are said to be met. If either or both conditions are not met, the criteria are deemed unmet. This structured approach ensures that the condition is accurately assessed based on the defined parameters.

The Diagnostic Criteria for Asymptomatic Microhematuria is a clinical tool designed to identify patients with asymptomatic microhematuria, a condition that can be an early indicator of serious urologic disease. This tool is particularly useful in primary care settings, where early detection can facilitate timely referral for further diagnostic evaluation and treatment.

The primary components of this diagnostic criteria include the presence of three or more red blood cells per high-power field in a properly collected urinary specimen, and the exclusion of an obvious benign cause. The diagnostic criteria are met if both these conditions are fulfilled. The presence of red blood cells in the urine is a key indicator of microhematuria, while the exclusion of benign causes helps to rule out conditions that may cause similar symptoms but do not require further urologic evaluation.

The result is determined based on these two components. If both conditions are met, the diagnostic criteria for asymptomatic microhematuria are fulfilled. If either condition is not met, the diagnostic criteria are not fulfilled, suggesting that the patient's symptoms may be due to a different cause. This tool thus aids in the accurate diagnosis of asymptomatic microhematuria, enabling appropriate management and treatment of the condition.
