1 -- Elevations in serum lactic acid dehydrogenase levels are associated with the presence of testicular cancer, and may be significantly elevated when metastatic disease is present. This laboratory test is a less specific indicator of testicular cancer than the human chorionic gonadotropin and alpha-fetoprotein. The levels alone are not sufficient to make a diagnosis of cancer and should promote further testing. Levels of serum lactic dehydrogenase would not be useful in diagnosis of spermatocele.
