Blood creatinine

A biochemical blood test, which includes an assessment of the creatinine index, is included in the list of screening examinations for pregnant women. The analysis is performed once in each trimester to monitor the work of the kidneys in conditions of increased stress on the female body. Since there is a risk of preeclampsia, exacerbation of chronic kidney disease and other problems during pregnancy, such a study cannot be neglected. Extragenital factors can cause reproductive disorders, therefore, in gynecology, creatinine analysis is also used in the complex diagnosis of infertility.

The study of the concentration of creatinine in blood samples is recommended if the following diseases are suspected:

• renal dysfunction in glomerulonephritis, pyelonephritis, hydronephrosis, urolithiasis and other diseases;
• metabolic disorders against the background of diabetes mellitus, hyperthyroidism, hyperfunction of the adrenal glands and pituitary gland;
• massive traumatic injuries of soft tissues with burns, prolonged compression syndrome;
• signs of impaired water-salt metabolism, hypocalcemic convulsions.

Affordable prices for a blood test for creatinine in Kyiv allow you to perform the procedure repeatedly to assess the dynamics of renal function. Doctors use such a study in patients with chronic kidney pathologies to track the effectiveness of the prescribed treatment, to detect the progression of the disease in time.

Patients who are going to take a blood test for creatinine should follow medical recommendations:

• 24 hours before the procedure, do not drink alcohol, do not abuse protein foods;
• stop eating 10-12 hours before donating blood;
• in the morning on the day of the examination, you can drink non-carbonated water; it is forbidden to drink coffee, tea, energy drinks, juices;
• Do not smoke 30 minutes before the test.

It is better to come to the procedure 10-15 minutes in advance, so that there is time to sit quietly and catch your breath. Do not donate blood immediately after exercise or when you are very excited.

If you are taking medication, you must inform your doctor before the test is scheduled. Vitamin C preparations, some antibiotics, NSAIDs and psychotropic drugs can interfere with the result, making the analysis unreliable. Therefore, at the time of the study, medications are canceled whenever possible.

The study takes place quite quickly, since it is enough to obtain a sample of venous blood for analysis. The patient comes to the clinic at the appointed time by appointment, visits the manipulation room. To test for creatinine, blood is taken from a vein in the arm in a standard way, the procedure takes several minutes. Our clinic employs experienced nurses who accurately puncture the vessel and do not cause pain to the patient.

After sampling, the blood is placed in a sterile tube and transferred to the laboratory in compliance with the correct temperature regime. The biomaterial is examined on a special analyzer, after which a form of results is formed.

Normally, the level of creatinine in women should not exceed 97 umol/l, for men the values ​​are higher - up to 115 umol/l. In pregnant women, a physiological decrease in this indicator is observed, which is associated with an increase in the volume of circulating blood and activation of the filtration function of the kidneys. Therefore, the range of creatinine during pregnancy is 35-70 umol/L.

If the analysis of the level of creatinine in the blood showed an excess of the indicator, it is required to consult a doctor as soon as possible, who can find out the root cause of the violations.

An increase in creatinine is possible in patients who prefer to eat meat and fish, eat few vegetables and cereals. A physiological increase in the indicator also occurs in athletes, people engaged in physical labor. Pathological causes of changes in the analyzes are the following conditions:

• acute renal failure (ARF) and chronic kidney disease (CKD);
• severe diseases of the cardiovascular system;
• taking drugs that have a toxic effect on the kidneys;
• bacterial infections of the kidneys;
• impaired renal blood flow;
• extensive damage to muscle tissue.

A decrease in the blood test for creatinine is much less common. This situation is possible with prolonged protein starvation, skeletal muscle atrophy, and blood thinning.

Pathological fluctuations in the level of creatinine occur in the late stages of renal pathology. For complex diagnostics, the study is combined with the measurement of blood urea, a general urine test, and the calculation of glomerular filtration rate (GFR). At the consultation, the doctor will assign the patient a list of clarifying studies, if necessary, will give a referral for examination to doctors of a different profile.

The study of biochemical parameters of blood has a low cost and is included in the program of routine diagnostics. Biomaterial samples are studied automatically using special analyzers, which allow for fast, accurate, and inexpensive diagnostics. In most cases, the test is carried out in combination with other indicators of blood biochemistry, so the doctor will be able to name the final amount after consultation.

If you need to donate blood for creatinine at an affordable price, contact the Dobrobut medical center. Experienced nurses, competent doctors, modern manipulation rooms, and a friendly atmosphere - here you will find everything you need for fast, comfortable, and accurate laboratory diagnostics.

Registration for tests is carried out by phone or upon request in the feedback form.
