At-home tests can be a convenient first step, but they don't replace an examination. Blood in semen in men 40 and over, recurrent bleeding, or any urgent symptom needs a clinician [NICE].
At-home STI tests
Useful if there's any chance of an infection, the most common identifiable cause under 40 [review]. Look for panels that include chlamydia and gonorrhea, CLIA-certified lab processing, and a clinician follow-up for positive results.

Men's health telehealth
Helpful when a local appointment is weeks away. A licensed clinician can take a history, order labs (urine, STI, PSA) and tell you whether an in-person exam is needed.
PSA blood tests
PSA is part of the workup from age 40 [RACGP]. Results need a clinician to interpret them: a normal PSA doesn't rule out cancer, and raised levels are often repeated [StatPearls].
Urine tests
Urinalysis is part of almost every evaluation [AAFP]. Home dipsticks can screen for signs of infection, but a lab urinalysis and culture are more reliable.
