This is very significant in regards to developing a differential diagnosis and eventually for the purposes of creating a treatment plan for the patient.Many causes may present as either visible hematuria or microscopic hematuria, and so the differential diagnosis is frequently organized based upon glomerular and non-glomerular causes. Glomerular hematuria
Glomerular causes include:

IgA nephropathy
Thin glomerular basement membrane disease
Hereditary nephritis (Alports disease)
Hemolytic uremic syndrome
Postinfectious glomerulonephritisCertain infectious agents like Group B Strep(strep pyogenes) can cause a person to get a very specific manifestation known as post-streptococcal glomerulonephritis. This manifestation results in a person having the symptom of cola-colored urine. Membranoproliferative glomerulonephritis
Lupus nephritis
Henoch-Shonlein purpura
Nephritic syndrome
Nephrotic syndrome
Polycystic kidney disease
Idiopathic hematuria

Non-glomerular hematuria
Visible blood clots in the urine indicate a non-glomerular cause. Non-glomerular causes include:

Urinary tract infections, such as pyelonephritis, cystitis, prostatitis, and urethritis
Kidney stones
Cancers, such as renal cell carcinoma and bladder cancer (particularly transitional cell carcinoma), and in men, prostate cancer
Urinary tract strictures
Benign prostatic hyperplasia
Renal papillary necrosis
Trauma or damage to the lining of the urinary tract
Intense exercise
Increased tendency to bleed due to acquired or genetic conditions (e.g. sickle cell disease or vitamin K deficiency bleeding) or certain medications (e.g. blood thinners)

Mimickers of hematuria
Pigmenturia
Not all red or brown urine is caused by hematuria. Other substances such as certain medications and certain foods can cause urine to appear red.Medications that may cause urine to appear red include:

Phenazopyridine
Nitrofurantoin
Doxorubicin
RifampicinFoods that may cause urine to appear red include:

Blackberries
Food dyes. Beets
Rhubarb
Fava beans

False positive urine dipstick
A urine dipstick may be falsely positive for hematuria due to other substances in the urine.
Hypokalemia is a low level of potassium (K+) in the blood serum. Mild low potassium does not typically cause symptoms. Symptoms may include feeling tired, leg cramps, weakness, and constipation. Low potassium also increases the risk of an abnormal heart rhythm, which is often too slow and can cause cardiac arrest.Causes of hypokalemia include vomiting, diarrhea, medications like furosemide and steroids, dialysis, diabetes insipidus, hyperaldosteronism, hypomagnesemia, and not enough intake in the diet. Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels below 3.5 mmol/L defined as hypokalemia. It is classified as severe when levels are less than 2.5 mmol/L. Low levels may also be suspected based on an electrocardiogram (ECG). Hyperkalemia is a high level of potassium in the blood serum.The speed at which potassium should be replaced depends on whether or not there are symptoms or abnormalities on an electrocardiogram. Potassium levels that are only slightly below the normal range can be managed with changes in the diet. Lower levels of potassium require replacement with supplements either taken by mouth or given intravenously. If given intravenously, potassium is generally replaced at rates of less than 20 mmol/hour. Solutions containing high concentrations of potassium (>40 mmol/L) should generally be given using a central venous catheter. Magnesium replacement may also be required.Hypokalemia is one of the most common water–electrolyte imbalances. It affects about 20% of people admitted to hospital. The word hypokalemia comes from hypo- under +  kalium potassium + -emia blood condition.
