One-Page Summary
Purpose of Testing
This annual laboratory evaluation documents overall health at age 80 and continues the long-term baseline established in previous years. The report demonstrates continued stability in kidney, liver, metabolic, thyroid, and cardiovascular health while identifying a very mild decrease in hemoglobin that merits observation in future laboratory studies. It remains an important pre-inflammatory reference approximately four years before the systemic inflammatory illness of 2021.
Major Findings
Metabolic Health
Results
- Glucose: 84 mg/dL
- Hemoglobin A1c: 5.6%
Interpretation
Glucose metabolism remained excellent. Hemoglobin A1c was at the upper limit of the normal reference range but remained below the laboratory threshold for prediabetes. Overall glycemic control continued to be very good.
Kidney Function
Results
- BUN: 23 mg/dL
- Creatinine: 0.96 mg/dL
- eGFR: 74 mL/min/1.73 m²
Interpretation
Kidney function remained stable and appropriate for age. There was no laboratory evidence of progressive renal impairment.
Liver Function
Results
- AST: 23 IU/L
- ALT: 15 IU/L
- Alkaline Phosphatase: 60 IU/L
- Bilirubin: 0.5 mg/dL
Interpretation
Liver function tests remained entirely within normal reference ranges, demonstrating continued healthy hepatic function.
Complete Blood Count
Results
- WBC: 4.8 ×10³/µL
- Hemoglobin: 12.5 g/dL (slightly below reference range)
- Hematocrit: 39.4%
- Platelets: 234 ×10³/µL
Interpretation
Most blood counts remained stable. Hemoglobin decreased slightly below the laboratory reference range (12.5 g/dL), representing the first mild reduction documented in the available laboratory history. Because the remaining blood indices were normal, this isolated finding was appropriate for continued observation rather than indicating a specific diagnosis. It later became a useful comparison point when anemia developed during the inflammatory illness in 2021.
Lipid Profile
Results
- Total Cholesterol: 162 mg/dL
- LDL Cholesterol: 91 mg/dL
- HDL Cholesterol: 62 mg/dL
- Triglycerides: 44 mg/dL
Interpretation
This was one of the strongest lipid profiles in the laboratory record.
Notable features included:
- LDL cholesterol within the laboratory reference range.
- High HDL cholesterol.
- Exceptionally low triglycerides.
This continued the favorable lipid pattern observed over previous years.
Thyroid Function
Result
- TSH: 1.910 μIU/mL
Interpretation
Thyroid function remained stable and within normal limits.
Prostate Screening
Result
- PSA: 3.1 ng/mL
Interpretation
PSA remained within the laboratory reference range, although it showed a gradual increase compared with prior years. Continued routine monitoring was appropriate.
Urinalysis
Routine urinalysis was normal.
Findings included:
- No protein
- No glucose
- No blood
- No infection
- Clear urine
Microscopic examination was not indicated because the screening urinalysis was normal.
Overall Interpretation
This report documents excellent overall health at age 80. Kidney function, liver function, thyroid function, urinalysis, glucose regulation, and cardiovascular risk markers remained stable. The lipid profile was particularly favorable, with LDL cholesterol in the normal range, high HDL cholesterol, and very low triglycerides. The only notable change was a slight reduction in hemoglobin, which became an important historical reference for comparison with the more significant anemia observed during the inflammatory illness several years later.
Longitudinal Significance
This report contributed to long-term trend analysis of:
- Blood counts
- Kidney function
- Liver function
- Lipid profile
- Glucose metabolism
- Thyroid function
- PSA
- Urinalysis
It also marks the first documented mild decline in hemoglobin, providing an important historical comparison for future hematologic changes.
Clinical Importance
⭐⭐ Stable Baseline with Early Hematologic Observation
This report demonstrates continued excellent health while documenting the first subtle reduction in hemoglobin. Although clinically minor at the time, it became valuable in retrospect when evaluating the anemia associated with the inflammatory illness that began in 2021.
Key Changes Since Previous Report
- Hemoglobin decreased from 13.3 to 12.5 g/dL, becoming slightly below the reference range.
- LDL cholesterol improved from 107 to 91 mg/dL.
- Total cholesterol decreased from 189 to 162 mg/dL.
- Triglycerides remained exceptionally low (45 → 44 mg/dL).
- HDL cholesterol remained high (73 → 62 mg/dL).
- Kidney function, liver function, thyroid function, glucose regulation, and urinalysis remained stable.
- PSA increased modestly from 2.7 to 3.1 ng/mL while remaining within the normal range.

Observation
This 2017 report stands out because it is the last annual laboratory evaluation before the more significant cardiovascular and inflammatory developments that followed in later years. Reviewing the 2013–2017 series together shows a remarkably consistent picture: stable organ function, excellent glucose regulation, a favorable lipid profile, and only a subtle decline in hemoglobin. That continuity makes these early reports especially valuable as the baseline against which the health changes beginning in 2018 and accelerating in 2021 can be understood.
