What labs are recommended during a Medicare annual wellness visit for a 65-year-old female?

Recommended Laboratory Tests for Medicare Annual Wellness Visit in a 65-Year-Old Female

For a 65-year-old female, the recommended laboratory tests during a Medicare Annual Wellness Visit include lipid profile, hemoglobin A1C, thyroid-stimulating hormone, serum creatinine with estimated glomerular filtration rate, and vitamin B12 if on metformin. 1

Core Laboratory Tests

• Lipid profile (total cholesterol, LDL, HDL, and triglycerides) - Recommended annually for cardiovascular risk assessment 1
• Hemoglobin A1C - For diabetes screening and monitoring, especially important if the patient has risk factors such as obesity, family history, or hypertension 1
• Serum creatinine with estimated glomerular filtration rate (eGFR) - To assess kidney function, particularly important in older adults 1
• Thyroid-stimulating hormone (TSH) - Recommended for thyroid disease screening, as thyroid disorders are highly prevalent in aging women 1, 2
• Vitamin B12 levels - Particularly if the patient is taking metformin 1

Additional Tests Based on Risk Factors

• Urinary albumin-to-creatinine ratio - For patients with diabetes, hypertension, or suspected kidney disease 1
• Liver function tests - Especially if the patient is on medications that affect liver function or has risk factors for liver disease 1
• Serum potassium levels - For patients on ACE inhibitors, angiotensin receptor blockers (ARBs), or diuretics 1

Screening Considerations by System

Cardiovascular Health

• Blood pressure measurement should be performed at every visit 1
• Consider baseline ECG if not previously done 3

Diabetes Screening

• For patients with prediabetes (A1C 5.7-6.4%), testing should be performed yearly 1
• For patients with normal results, testing should be repeated at minimum every 3 years 1

Cancer Screening

• Cervical cancer: Pap testing can be discontinued after age 65 if the patient has had adequate prior screening with normal results (three consecutive negative tests in the past 10 years) 1, 4
• Breast cancer: Annual or biennial mammography should be discussed 1
• Colorectal cancer: Annual fecal occult blood testing and/or flexible sigmoidoscopy or colonoscopy at appropriate intervals should be reviewed 1

Cognitive Assessment

• The Medicare Annual Wellness Visit requires assessment for cognitive impairment, though specific laboratory tests are not mandated 1, 5
• The Alzheimer's Association recommends a structured approach including patient observation, unstructured queries, and possibly structured cognitive assessment tools 5

Common Pitfalls to Avoid

• Overlooking thyroid screening: Thyroid disorders are common in older women and symptoms can mimic normal aging 2
• Missing vitamin B12 deficiency: Particularly important to check in patients taking metformin 1
• Discontinuing cervical cancer screening too early: Ensure the patient meets criteria for cessation (age ≥65 with adequate prior normal screening) 4
• Underutilizing the Medicare Annual Wellness Visit: This visit provides an opportunity for comprehensive preventive care assessment that is often underutilized 6, 7
• Failing to assess kidney function: Age-related decline in renal function makes monitoring eGFR important for medication management 1

Frequency of Testing

• Most laboratory tests should be performed annually during the Medicare Annual Wellness Visit 1
• Some tests may be needed more frequently based on abnormal results or medication changes 1
• For patients with normal results and no risk factors, certain tests like lipid profiles may be performed less frequently at the physician's discretion 1
