Initial Evaluation Steps
Doctors begin with a detailed medical history and physical exam to identify symptoms of BPH. This includes assessing urinary habits and conducting a digital rectal exam (DRE) to evaluate prostate size. The goal is to distinguish BPH from other potential causes of urinary symptoms.
Key Laboratory Tests
Urinalysis is a common test used to rule out infections or other causes of symptoms. Prostate-specific antigen (PSA) levels might also be checked, although it's not always necessary for diagnosing BPH. These tests help ensure that symptoms aren't due to another condition like prostate cancer.

Advanced Diagnostic Tools
In some cases, further tests such as bladder scans or ultrasound may be used to measure post-void residual volume. These tests help assess whether the bladder is emptying properly, which is crucial for determining the severity of BPH.
