Table 3. Hemoglobin A1C percentage, C-reactive protein, erythrocyte sedimentation rate, thyroid stimulating hormone, free thyroxine (T4), and vitamin B12 levels. The table shows the values of tests performed to examine the patient’s diabetes status, determine the body’s inflammatory state (CRP, ESR), and rule out secondary causes of muscle weakness and imbalance (hypothyroidism and low vitamin B12 levels). The patient’s test results were normal except for CRP, with values indicative of an autoimmune process.
| Test | Value | Normal range |
|---|---|---|
| Hgb A1C (%) | 5.4 | |
| CRP (mg/L) | 4.69 | 0.00–3.00 |
| ESR (mm/h) | 8 | 0–20 |
| TSH (µIU/mL) | 0.861 | 0.550–4.780 |
| Free T4 (ng/dL) | 1.150 | 0.890–1.760 |
| B12 (pg/mL) | 668 | 200–1100 |
| Hgb A1C% – hemoglobin A1C percentage; CRP – C-reactive protein; ESR – erythrocyte sedimentation rate; TSH – thyroid stimulating hormone; Free T4 – thyroxine; B12 – vitamin B12. | ||
