Tammy R., an 18 year-old college freshman, went to the University Health Center complaining of a sore throat, fever, and exhaustion. The physician noted swollen lymph glands and ordered a CBC; chemistry profile, strep screen, and monotest. Results show: CBC: Chemistry: WBC: 14.5 5-10x 109/L Sodium: 141 136-145 mEq/L RBC: 5.35 4.0-5.0 x 1012/L Potassium: 4.4 3.5-5.0 mEq/L Hgb: 14.8 12.0-16.0 g/dL Chloride: 107 101-111 mEq/L Hct: 45 36-46% Co2: 27.0 24.0- 34.0 mEq/L MCV: 84 80-100fL Glucose: 92 80-120 mg/dL MCH: 28 26-34pg T. Bili: 1.9 0.2-1.2 mg/dL MCHC: 33 31-37% AST: 89 5-40 IU/L PLTS: 225 150-400 x 103 ALT: 80 6-37 IU/L Neut: 28 25-60% T. Prot: 6.5 6.0-8.4 g/dL Band: 0 0-10% BUN: 15 7-24 mg/dL Lymph: 40 20-50% Creat: 0.9 0.5-1.2 mg/dL Mono: 6 2-11% Ca: 8.8 8.5-10.5 mg/dL Eos: 0 0-8% Alb: 3.9 3.5-5.0 g/dL Baso: 1 0-5% Serology and Microbiology Results: Serology: Monotest Positive (Ref: negative) Microbiology: Strep test Negative (Ref: negative) 1. List the abnormal lab results: 2. Based on Tammy’s history (symptoms) and lab results, what is the probable diagnosis? 3. If the monotest were negative, would you change your answer? Explain why or why not. (2) 4. What is the test detecting? Describe them. (2) 5. What class of antibody is the test detecting? 6. Is this an acute or chronic case? Which antibody would be present in each case? (2)
