Hi Rico,


Kidneys are important organs in the body that function to filter blood and separate toxins, control the balance of electrolytes and fluids in the body. For that kidney health is important to be maintained from an early age. Some disorders of the kidney organs can occur such as kidney infections, kidney cysts, kidney stones, kidney cancer and also kidney failure. This condition is influenced by many things such as food intake, daily fluid consumption, body weight, blood pressure,


To determine the condition of the kidneys, several examinations can be carried out such as blood lab tests to assess kidney function, urine examination, ultrasound or scanning with a CT scan. Examination of urine and kidney function itself can be done without stopping the drugs that are consumed daily. For the urine test itself, there are various types and techniques, some are done using morning urine or urine at time.


Sampling also varies, so it is necessary to ask your doctor or lab staff about preparation before taking the test, but some urine tests do not require special preparation but it is better if you are married to avoid having sex at least 12 hours before the examination. Kidney function blood lab tests usually require preparation for fasting between 8-10 hours by consuming water. This examination will assess several things such as urea, creatinine, uric acid and glomerular filtration rate which will later be able to describe the condition of kidney function whether it is good or not.


Hope it is useful,
