Purpose of Testing

This annual laboratory evaluation documents overall health at age 77 and provides the second baseline report in the Health Inventory. It expands upon the 2013 evaluation by including Hemoglobin A1c, urinalysis, creatine kinase, and magnesium testing, allowing broader assessment of metabolic, cardiovascular, renal, endocrine, and general health.

Major Findings

Metabolic Health

Results

  • Glucose: 80 mg/dL
  • Hemoglobin A1c: 5.9%
Interpretation

Fasting glucose remained excellent. However, Hemoglobin A1c increased into the laboratory’s “increased risk for diabetes” category (5.7–6.4%), suggesting the need for continued long-term monitoring despite normal fasting glucose.

Kidney Function

Results

  • BUN: 23 mg/dL
  • Creatinine: 0.93 mg/dL
  • eGFR: 79 mL/min/1.73 m²
  • BUN/Creatinine Ratio: 25 (slightly elevated)
Interpretation

Overall kidney function remained excellent. The mildly elevated BUN/Creatinine ratio occurred despite a normal creatinine and preserved eGFR and was not accompanied by other evidence of kidney disease.

Liver Function

Results

  • AST: 39 IU/L
  • ALT: 28 IU/L
  • Alkaline Phosphatase: 67 IU/L
  • Bilirubin: 0.4 mg/dL
Interpretation

Liver function remained within normal limits, although AST was near the upper end of the reference range. No evidence of hepatic dysfunction was present.

Complete Blood Count

Results

  • WBC: 6.1
  • Hemoglobin: 12.8 g/dL
  • Hematocrit: 39.3%
  • Platelets: 209
Interpretation

Blood counts remained stable with no evidence of infection or significant anemia. This report continues to establish the healthy hematologic baseline that preceded the inflammatory illness several years later.

Lipid Profile

Results

  • Total Cholesterol: 215 mg/dL
  • LDL Cholesterol: 138 mg/dL
  • HDL Cholesterol: 63 mg/dL
  • Triglycerides: 68 mg/dL
Interpretation

Compared with the 2013 report, total cholesterol and LDL cholesterol increased into the elevated range. Despite this change, HDL cholesterol remained high and triglycerides remained low—features that would become a consistent pattern throughout subsequent years.

Thyroid Function

Result

  • TSH: 0.647 μIU/mL
Interpretation

Thyroid function remained within the normal reference range.

Cardiac Marker

BNP

Result

  • 37.9 pg/mL
Interpretation

BNP was well within the normal range and lower than the 2013 value, providing continued evidence of stable cardiac status at the time of testing.

Prostate Screening

Result

  • PSA: 2.3 ng/mL
Interpretation

PSA remained within the normal reference range and was essentially unchanged from the previous year.

Urinalysis

Routine urinalysis was normal.

No evidence of:

  • Proteinuria
  • Glucosuria
  • Hematuria
  • Urinary tract infection

Microscopic examination was not indicated because the screening urinalysis was normal.

Additional Testing

Creatine Kinase (CK)
  • 110 U/L (normal)
Magnesium
  • 2.1 mg/dL (normal)

These results showed no evidence of muscle injury and normal magnesium status.

Overall Interpretation

This report documents excellent overall health at age 77, with stable kidney, liver, thyroid, blood count, urinary, and cardiac findings. The two laboratory changes warranting future observation were the increase in LDL cholesterol and total cholesterol, and the Hemoglobin A1c of 5.9%, which falls within the laboratory’s increased-risk category for diabetes. These findings became important reference points for evaluating long-term cardiovascular and metabolic trends.

Longitudinal Significance

This report contributed to the long-term trend analysis of:

  • Kidney function
  • Liver function
  • Blood counts
  • Lipid profile
  • Glucose metabolism
  • Thyroid function
  • Cardiac biomarkers
  • PSA
  • Urinalysis

It represents the first documented shift toward a persistent elevated LDL cholesterol pattern while maintaining favorable HDL cholesterol and triglyceride levels.

Clinical Importance

⭐⭐ Early Trend Identification

This report documents the beginning of the long-term lipid pattern that would continue for many years while confirming continued stability in nearly every other major body system.
