Understanding and Applying the Fena Formula in Kidney Health Care and Maintenance

If you are a kidney dieter, the question that probably comes to mind is, "How to calculate Fena Formula?" Well, it is quite easy if you know how to calculate urine sodium and chloride excretion. The Fena formula is presented below on how to calculate fena formula loss of sodium. Fena formula = Fena (Urea) x 100, where Urea is the component of urine that is most concentrated, Urea is calculated as (Urine Sodium) x 100. Thus, one is able to estimate the amount of sodium in his blood.

There are various ways to use fena formula, which is widely used by people who are diabetics and want to maintain healthy blood-sugar levels. Such people are prone to high blood-sugar levels, which may result to various health complications. Such complications include heart attack and diabetes. To help them learn how to calculate fena formula, they can use a little calculator. A fena calculator is a type of computerized calculator that is available in the market for use by people who have diabetes or are concerned with their blood-sugar levels.

Various factors are considered when computing the equilibrium of the fena formula, which is the main function of the calculator. One of such factors is the percentage of urine excretions that are of the acidic variety. Another factor is the plasma sodium concentration, which shows how concentrated the salt is in the blood. The third factor is the mean daily albumin concentration, which depicts how much of the albumin is currently in the plasma. Other factors considered in computing the equilibrium of the fena formula include the percentage of water in the body as well as the total amount of blood in the body. All these factors are significant when calculating the equilibrium of the fena formula.

There are a couple of methods by which one can use fena calculators. One of these methods is the resting excretion method. This is the most common way by which the fena equation is computed. In this method, the fena calculator is programmed to automatically calculate the fena value after taking a sample of the patient's plasma. The sample can be taken in the early morning after one hour.

The plasma sodium concentration is then compared with the normal value of the blood as indicated on the laboratory data. If the concentration of the salt is significantly lower than the normal value, the diagnosis of hyponatremia has been established. Hyponatremia is a condition in which the sodium level in the blood exceeds the normal level.

Once the diagnosis has been established, the next step is to determine the probable cause of the condition. Hyponatremia is considered to be related to the decrease of the volume of the urine as indicated by the serum creatinine. A low urine sodium level may also be caused by decreased water and electrolyte balance. To be able to compute the end formula from these results, the urine sodium level must be calculated using the following equation: where H20O is the hydrochloric acid in milligrams of sodium chloride in the patient's urine, pH is 7.4, and TC = Constant tension lymph flow rate in units of minutes. Other factors that influence the urine sodium level include the food consumed, medication, fluid retention, exercise, smoking, vomiting, and pregnancy.

The third type of fena equation used is the fractional excretory function (FDFE) formula. This is a more complex equation. It involves two separate functions, namely, the fractional transport function and the fractional expiry function. These two functions are used to calculate the serum TC level and the serum creatinine level. The FDFE equation can be written down as follows: where Tc is the triphosphate concentration in the body fluids, Tp is the serum potassium level, and IE is the fractional excretory function.

The last but not least is the calibration/calibration function. This calculator is used to adjust the pre-renal fluid samples before they are measured. The results of the pre-renal fluid calibration/calibration are then entered into the fena equation. If your blood sodium levels are within the normal range (not too low and not too high), the normal values for TC, H2O and Na+ should be displayed on your LCD display monitor. If the blood sodium levels are outside the normal range, then the percentage of correction for the sample must be applied. This calculation can be done manually or using one of the many sophisticated laboratory computer software programs that can calculate the end value for you.
