Why Should Kidney Function Tests?

Tests for renal function evaluation
When kidney damage persists for a variety of reasons, it can lead to kidney failure. One of the reasons for this is that patients have been taking drugs for a long time and using drugs that affect the kidneys without knowing it or checking their kidney function during medication. Renal failure is a condition of sudden, progressive deterioration called acute or gradual renal failure called chronic renal failure. Acute renal failure, kidney function may recover. Chronic renal failure is a gradual decline and eventually a complete loss of function, which requires therapeutic measures to support kidney function in order for the body to survive

.
The common clinical symptoms of kidney failure
Renal failure is clinically evident when the damage is> 90% of the active unit of both kidneys. Therefore, the clinical manifestations are very difficult, only detected in acute or chronic renal failure in the late stages.
The amount of urine may decrease or increase
Symptoms of excess water: edema, hypertension, heart failure, pulmonary edema, cerebral edema, .
Symptoms of increased toxins in the blood: nausea, vomiting, anorexia, myalgia, arthralgia, arrhythmia, difficulty sleeping, skin rash .



...
Symptoms of anemia: pale skin, dizziness ..
Symptoms of the disease cause kidney failure: diarrhea, acute bleeding, back pain, abdominal pain, difficulty urinating
How do kidney function tests work?
An accurate assessment can be made by kidney biopsy, reading the kidney unit structures under a microscope. The tests only measure relative kidney function, so a combination of tests are needed.
Biochemical tests:
Creatinin, BUN (Blood Urea Nitrogen) are products of protein metabolism for the body, which are excreted by the kidneys in the urine. Normal value, BUN: 6-24 mg / dL (equivalent to 2.



.5-8 mmol / L), creatinine: 0.5-1.2mg / dL (equivalent to 45-110 mmol / L), when functional Worsening renal function these indicators will increase in the blood.
Often urea / blood and urea / urine, creatinine / blood and creatinine / urine tests in parallel to give an accurate result, thus calculating creatinine clearance Normally, creatinine clearance is 70-120mL / min, decreased creatinine clearance indicates impaired renal function.
Electrolytes: assessing renal dysfunction, causing electrolyte imbalance in the body.
Alkaline balance disorders
Blood uric acid
General analysis of urine
Quantification of 24-hour urine protein
Serum albumin
Plasma total protein
General blood cell analysis
Stomach supersonic
CT scan of the abdomen
Radiation of kidney by radioactive isotope
Assign other kidney function tests
Periodic health checks should be done every year, in addition to testing to test for parasitic helminths, such as orientation tests: biochemical blood test, total urine analysis, blood count, abdominal ultrasound to promptly detect kidney problems.
