Kidney Function Tests
Medical
tests play a very important role in the evaluation of renal function in
many diseases that affect the college, as the follow-up kidney patients
and predict ultimatum condition they have and these analyzes are:(1) measuring the urea (Urea)Urea
is the product of President and final metabolism of proteins in
mammals, consists of urea in the liver and then passes into the blood to
the kidneys, where he graduated with urine and interference in the
formation of urea from ammonia (NH3) toxic, which consists of the
demolition of acids Alaminihrgm that the level of urea in the blood is
an indicator of non- sensitive
function of renal However, the ease of measurement made of the tests
common insensitivity Hmaalachtbar that he must lose more than 50% of the
function glomeruli renal even Atathermistoy urea in the blood,
moreover, there are many reasons non-renal origin enable rising urea in
the blood, as that the level of urea in the blood is affected by proteins in the food and the amount of Rashih glomerular kidney.- The level of urea in the blood ranges from 20 to 40 mg / 100 ml blood (3.5 - 7 mmol / L)- The level of urea in the blood NatroyjanaBlood Urea Nitrogen (BUN)- The range of 8-25 mg / 100 ml blood (0.9 - 8.9Mmol / L)- The level of concentration of urea in the urine ranged between20 to 40 mg / 100 ml blood, and in infants between 5-15 mg / 100 ml blood, and children from 5 to 20 mg / 100 ml bloodIncrease the level of urea in the blood in the following cases: -- Inflammation of acute and chronic renal- Renal Failure- Obstructive urinary- Gastrointestinal bleeding- Trauma and fall of the adrenal gland- Cases of dehydration, so as to have a large amount of fluidSuch as that occurs in persistent vomiting and severe diarrheaMercury poisoning and heavy metal salts of someOtherDecreasing the level of urea in the blood in the following cases:Liver
disease developed, in which case Ttkonmadh ammonia and fails the liver
to convert to Paulina Due to the severity of the disease, and
Taatdhaafalkhtorh in the presence of high concentrations of urea,
because the ammonia gas is extremely toxic, which is spreading in the
whole body and the impact Serious is on the brain as it leads to
complete paralysis of the brain and Faihalh cerebral
palsy resulting from increasing the proportion of ammonia enters the
patient in a coma Hepatic Coma intermittent, but with the increase in
the proportion of ammonia in the blood may lead to the patient in a coma
long time may lead to Alovahxiaodh rate of dialysis industry and this
affects the rate of urea in the blood, where there are few to up to less than normal.Reasons for the increase Tzakiz urea in the urine:Increasing concentration of urea in the urine when you eat a diet rich in protein, and in cases associated with increased protein catabolism in the body such as fever, Marzalskr untreated hyperthyroidism and thyroid gland.Concentration causes a decrease of the proportion of urea in the urine
Less than the proportion of urea in the urine when you eat a poor diet of proteins, and in the building of proteins such as pregnancy and lactation, and in cases of liver failure and kidney failure.(2) measurement of creatinine Creatinine: -The measurement of creatinine indicator of more honest for the safety of the kidney function of measuring urea in the blood, a creatine anhydrous, where is produced from phosphate creatine after the phosphate group then passes blood to the kidneys to come out with urine and appropriate concentration blood and urine directly proportional to the size of the muscles of the body and not affected by eating, and constant focus for the past 24 hours, so it is best to test the meter and Zifahalklah.- The level of creatinine in the blood varies between 0.5 -1.5 mg per 100 ml blood (60-123 micromol / L)- Concentration of creatinine in the urine of about 1.5 g / 24 hours in males.The concentration of creatinine in the urine of about 1.0 g / 24 hours in females because of the different muscle size in both male and femaleIncrease the level of creatinine in the blood may result in:- Cases of acute renal failure and chronic- Obstructive urinaryWhile creatinine ratio of at least 0.5 g / 100 mlBlood does not mean any diagnostic importance.(3) creatinine clearance Creatinine Clearance Test: -This analysis is more accurate than previous analyzes which reveals the renal function in the past 24 hours, and also connects between creatinine ratio in both blood and urine within 24 hours.- Rate in males ranging between 90 to 140 ml / min- While the female percentage in the range between 80 to 125 - ml / min
Reduced creatinine clearance in all cases where Altinkhvd kidney function such as:- Pressure drop- Shortness of renal artery(4) measurement of uric acid (uric acid) (Uric Acid) Uric AcidIs the final product of the metabolism of purine Purine in humans, and enters in the composition of purine Ahamaudhalnowih includes adenine and guanine Adinine Guanine. Change the level of uric acid in the blood than an hour to another, and one day to another day, and that many factors affect the uric acid from fasting Ataiwalenoaah food, and the level of acid Alorett acid in the blood ranges from 3 to 7 mg per 100 ml blood in males (0.18 - 0.53) mmol / l.In females the level of uric acid ranged between 2-6 mg ml blood (0.15 - 0.45) mmol / Traikhrj of uric acid by the kidneys as about 80% of uric acid Mnhamad formed in the body comes out with the urine, and the part Ketbaka come out with yellow.The amount of uric acid from acid in the urine emerging between300 to 700 mg / 24 hours (1.2 to 6.3 mmol / 24 hours)Half of this amount comes from purine metabolism external (of eating) and the other half of the purine procedure (body cells), and therefore must Kamihhamad when measuring uric in the urine that the food is free of purine before and during the 24 hours for the collection of urine.Increase the level of uric acid in the blood in Alhalataltalah:Gout Gout- Renal Failure- An overactive thyroid gland- In some alcoholicsLeast the level of acid uric acid in the blood:- Cases of acute hepatitisWhile an at least concentration of uric acid in urineIn kidney disease
