The array of important laboratory services available to Skyline patients include, but are not limited to, the following.

Prostate-Specific Antigen Test (PSA Test)

This is a simple blood test that can detect cancer of the prostate early, when it can be most effectively treated.  PSA is a substance made by cells in the prostate gland. PSA is mostly found in semen, but can also be found in the blood. Most healthy men have levels under 4 nanograms per milliliter of blood. The chance of having prostate cancer goes up as the PSA level increases.  Skyline Urology physicians recommend that men obtain a baseline serum PSA at 40-45 years of age.  Patients are encouraged to talk to their physician about the recommended screening guidelines for prostate cancer

Bladder Cancer DNA Test (Urine FISH)

The innovative FISH test – which stands for fluorescence in situ hybridization (FISH) -- utilizes a urine sample and colored dyes that allow for detection of cancer-promoting abnormalities under a fluorescent microscope in the laboratory.  Detection of relevant genetic abnormalities can aid in the diagnosis of bladder cancer.  In fact, FISH testing of urinary cells is a powerful test that can detect up to 95% of aggressive bladder cancer. FISH also may be used to detect a recurrence of bladder cancer several months earlier than standard testing.

Urine Cytology

Urine cytology is used along with other tests and procedures to diagnose urinary tract cancers. The test itself looks for abnormal cells in the urine.  Most often, urine cytology is used to diagnose cancer of the bladder, but it also may be helpful in detecting cancers of the kidney, prostate, ureter and urethra.  Your physician may recommend this test if blood has been detected in your urine.  Additionally, urine cytology may help detect the recurrence of bladder cancer in a patient who has been previously treated for this disease.


This medical test is most commonly performed by a surgeon or an interventional radiologist using a sampling of cells or tissues for evaluation in the laboratory.  The evaluation seeks to determine the presence of extent of a disease such as cancer.  In the lab, the tissue is examined by a pathologist.  For urology patients, a biopsy may be performed to confirm or rule out a diagnosis of prostate cancer or kidney cancer, for example.  In some cases, a biopsy can be performed conveniently in your physician’s office.  In cases requiring some anesthesia, your physician will refer you to an alternate location for your procedure.
