Diabetic Ketoacidosis (DKA): Although the patient is afebrile and has a negative ketone test, the presence of >2000 urine glucose, abdominal pain, and cloudy urine suggests a possible diagnosis of DKA, especially considering the patient's age and symptoms. However, the absence of ketones and the patient being afebrile may indicate an alternative diagnosis.

Urinary Tract Infection (UTI): The patient's symptoms of cloudy urine, abdominal pain, and trace blood in the urine are consistent with a UTI. The high glucose level in the urine could be contributing to the development of the infection.
Pyelonephritis: Similar to UTI, pyelonephritis could explain the patient's symptoms, including abdominal pain and cloudy urine. The high glucose level in the urine may be a contributing factor.
Nephrolithiasis: The patient's abdominal pain and cloudy urine could be indicative of kidney stones, especially if the stones are causing an obstruction or infection.

Sepsis: Although the patient is afebrile, sepsis should be considered as a possible diagnosis, especially if the patient's condition worsens or if there are signs of organ dysfunction. Sepsis can be life-threatening if not promptly treated.
Appendicitis: Abdominal pain and cloudy urine could be indicative of appendicitis, especially if the appendix is ruptured and causing a urinary tract infection.
Obstructive Uropathy: An obstruction in the urinary tract, such as a kidney stone or tumor, could cause abdominal pain and cloudy urine.

Tubulointerstitial Nephritis: This rare condition could cause abdominal pain and cloudy urine, especially if the patient has a history of medication use or infection.
Renal Tubular Acidosis: This rare condition could cause abdominal pain, cloudy urine, and an abnormal urine pH, as seen in this patient.
