Kidney Disorders Blood Test

What is Kidney Disorders?

Kidney disorders encompass conditions affecting the kidneys' ability to filter waste, regulate fluids, and maintain electrolyte balance. They are caused by chronic disease progression, acute injury, inflammation (nephritis), diabetes, hypertension, and autoimmune conditions damaging kidney tissue. The Urinalysis Complete Profile is the most important test for kidney disorders because it evaluates kidney concentration ability and detects protein loss indicating dysfunction.

What causes kidney disorders?

Kidney disorders are caused by chronic diseases like diabetes and hypertension, acute injuries from infections or toxins, autoimmune diseases like lupus, genetic conditions like polycystic kidney disease, and prolonged use of certain medications. Diabetes damages the tiny blood vessels in the kidneys over time, while high blood pressure strains kidney tissue and reduces filtering capacity. Acute kidney injury can develop suddenly from severe dehydration, blood loss, infections, or exposure to contrast dyes used in medical imaging.

What is the best test for kidney disorders?

The Urinalysis Complete Profile is the most important test for kidney disorders because it detects protein in urine (proteinuria), measures urine concentration ability through specific gravity, and identifies cellular debris or casts indicating kidney damage. This test reveals early signs of kidney dysfunction before symptoms appear. The Chloride blood test is essential for detecting electrolyte imbalances caused by impaired kidney function, while the Protein Electrophoresis test measures total blood protein levels that drop when kidneys leak excessive protein into urine. Together, these tests provide a comprehensive assessment of kidney filtration capacity, electrolyte regulation, and protein handling.

When should I get tested for kidney disorders?

You should get tested if you notice swelling in your ankles, feet, or hands, experience persistent fatigue or weakness, see foamy or bubbly urine indicating protein loss, notice blood in your urine, or have difficulty urinating or reduced urine output. People with diabetes, high blood pressure, heart disease, or a family history of kidney disease should get tested regularly even without symptoms. You should also test if you take medications like NSAIDs or certain antibiotics long-term, as these can damage kidneys over time.

What are the symptoms of kidney disorders?
Kidney disorder symptoms include persistent fatigue and weakness, swelling (edema) in the legs, ankles, feet, or face, changes in urination patterns like increased frequency at night or decreased output, foamy urine from protein leakage, and blood in urine making it pink or cola-colored. You might experience loss of appetite, nausea, vomiting, difficulty concentrating, muscle cramps, dry and itchy skin, and shortness of breath from fluid buildup. Many people have no symptoms in early stages, which is why testing is crucial for those with risk factors like diabetes or high blood pressure.
Who is at risk for kidney disorders?
People with diabetes and high blood pressure face the highest risk for kidney disorders, as these conditions damage kidney blood vessels over time. You are at increased risk if you have heart disease, obesity, a family history of kidney disease, are over age 60, have autoimmune diseases like lupus, suffer from recurrent urinary tract infections, or use NSAIDs or certain prescription medications regularly. African Americans, Hispanics, Native Americans, and Asian Americans have higher genetic susceptibility to kidney disease. Smokers and people with a history of acute kidney injury also face elevated risk.
What happens if kidney disorders are left untreated?
Untreated kidney disorders progress to chronic kidney disease and eventually end-stage renal disease requiring dialysis or kidney transplant. Damaged kidneys cannot remove waste products and excess fluid, leading to dangerous toxin buildup in the blood (uremia), severe anemia from reduced production of red blood cells, bone disease from calcium and phosphorus imbalances, and cardiovascular complications including heart attack and stroke. You may develop uncontrolled high blood pressure that further damages kidneys, electrolyte imbalances causing heart rhythm problems, and fluid accumulation in the lungs (pulmonary edema) making breathing difficult.
Can kidney disorders be diagnosed with a blood test?
Kidney disorders can be diagnosed through blood tests that measure creatinine and blood urea nitrogen (BUN) to calculate glomerular filtration rate (GFR), which indicates how well kidneys filter waste. Blood tests also detect electrolyte imbalances like abnormal chloride, potassium, and sodium levels, measure blood protein levels that drop when kidneys leak protein, check for anemia common in kidney disease, and assess calcium and phosphorus levels affected by kidney dysfunction. Combined with urine tests like the Urinalysis Complete Profile, blood work provides a comprehensive picture of kidney function and helps identify the type and severity of kidney damage.
How is kidney disorders treated?
Kidney disorder treatment focuses on managing underlying causes and slowing disease progression through blood pressure control with ACE inhibitors or ARBs, blood sugar management for diabetic patients, dietary modifications including reduced sodium, protein, and potassium intake, and medications to treat complications like anemia, bone disease, and cholesterol. Treatment may include diuretics to reduce fluid buildup, phosphate binders to control mineral levels, and erythropoietin-stimulating agents to boost red blood cell production. Advanced kidney disease requires dialysis (hemodialysis or peritoneal dialysis) or kidney transplant when kidneys can no longer sustain life.
How can I prevent kidney disorders?
You can prevent kidney disorders by controlling blood sugar if you have diabetes, managing blood pressure through diet and medication, maintaining a healthy weight, exercising regularly, limiting salt intake, staying well-hydrated with water, avoiding excessive use of NSAIDs like ibuprofen, and not smoking. Eat a kidney-friendly diet rich in fruits, vegetables, and whole grains while limiting processed foods. Get regular checkups including blood pressure monitoring and kidney function tests if you have risk factors. Treat urinary tract infections promptly, limit alcohol consumption, and work with your doctor to monitor medications that may affect kidney function.
What natural remedies help with kidney disorders?
Natural approaches to support kidney health include staying well-hydrated with 8-10 glasses of water daily to help kidneys flush toxins, reducing sodium intake to below 2,300 mg per day to ease kidney workload, consuming antioxidant-rich foods like berries, red grapes, and leafy greens, and limiting protein intake to reduce kidney strain in advanced disease. Herbs like dandelion root may support kidney function, though you should consult your doctor before taking supplements. Regular moderate exercise improves blood flow to kidneys, while stress reduction through meditation or yoga may help lower blood pressure. These natural approaches complement medical treatment but cannot replace it for established kidney disease.

What this means

Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
