He went to the emergency room, where urinalysis, blood work, and other tests were conducted, providing the following data:

#### Urinalysis Results
- **Appearance:** Red to brown
- **Specific gravity:** 1.025
- **Blood:** Positive
- **Glucose:** Negative
- **Protein:** Mild

#### Renal Function Tests
- **GFR (glomerular filtration rate):** 40 mL/min
- **RBF (renal blood flow):** 280 mL/min

#### Hematology Results
- **Serum sodium:** 125 mEq/L
- **Serum potassium:** 6 mEq/L
- **Serum creatinine:** 2.6 mg/dL
- **BUN (Blood Urea Nitrogen):** 24.0 mg/dL
- **pH (arterial):** 7.32
- **Hematocrit:** 25%

This data will aid in the diagnosis and further understanding of the patient's condition.
