He reports that he has been feeling well and has no specific complaints, except for some trouble “emptying my bladder.” Vital signs (VS) at this visit are 148/88, 82, 16, 96.9° F (36.1° C). He had a CBC and complete metabolic panel (CMP) completed 1 week before his visit, and the results are listed below
.1. What can you tell S.M. about his lab work?

Sodium       140 mEq/L
Potassium   4.2 mEq/L
Chloride100   mEq/L
Bicarbonate   26 mEq/L
BUN       19 mg/dL
Creatinine   0.8 mg/dL
Glucose       94 mg/dL
RBC5.2       million/mm3
WBC       7400/mm3

Hct       46%
Platelets       348,000/mm3
Prostate-specific antigen (PSA)   0.23ng/mL
Urinalysis               WNL

2. What is the significance of the PSA result?

3. What other specific examination will S.M. need to have along with the PSA?

Answer 1

1. What can you tell S.M. about his lab work?

         Prostate Specific Antigen level is increased. All other test results are normal. PSA        levels of 4.0 ng/mL and lower is considered as normal.

2. What is the significance of the PSA result?

Increased level of PSA indicates prostatitis or urinary tract infection. Sometimes it indicates prostate cancer.

3. What other specific examination will S.M. need to have along with the PSA?

Along with PSA the following tests has to do.

• Ultrasound
• · Magnetic resonance imaging (MRI)
• · Collecting a sample of prostate tissue. (prostate biopsy). The tissue sample is analyzed in a lab to determine whether cancer cells are present.
