**How to calculate eGFR**

eGFR (Non-African American) = 175 x ([Creatinine])-1.154 x (Age)-0.203 x 0.742

eGFR (African American) = 175 x ([Creatinine])-1.154 x (Age)-0.203 x 0.742 x 1.210

**eGFR Calculation in Prolis**

eGFR (Non-African American) = 175*({306})^-1.154*(@Age@)^-0.203*0.742 if 306 is the Test ID of Creatinine, in PROLIS.

eGFR (African American) = 175*({306})^-1.154*(@Age@)^-0.203*0.742 if 306 is the Test ID of CreatinineL, in PROLIS.

The HbA1c test result is considered the best diabetes management tool. HBA1c result reported as percentage to provide the average blood glucose.There is a new method to report HbA1c results called estimated average glucose(eAG), which is easier for patients to understand as it is closer to the results given by patient’s glucose meters.

**Estimated Average Glucose Formula**

eAG = 28.7 x [Hemoglobin A1C] – 46.7

**Estimated Average Glucose Calculation in Prolis**

eAG = 28.7 * {339} – 46.7 if 339 is the Test ID of Hemoglobin A1CL, in PROLIS.

The amount of Globulin and Albumin proteins are measured through total protein test. It can be used as routine blood testing or may be used to track kidney or liver disease, unexpected weight loss, or fatigue.

**Globulin Calculation**

Globulin = [Total Protein] – [Albumin]

**Globulin Calculation in Prolis**

Globulin = {311} – {312} if 311 is the Test ID of Total Protein and 312 is the Test ID of Albumin, in PROLIS.

If total bilirubin is abnormal, direct and indirect bilirubin measurement is very important. This test may be done as part of routine blood testing to track liver or blood related diseases.

**KT/V Natural Log Calculation in Prolis**

KT/V Natural Log = (-1) * Log(({422} / {305}) – (0.008 * {191} / 60)) + ((4 – (3.5 * {422} / {305})) * (({189} – {190}) / {190})) if 422 is the Test ID of Post BUN and 305 is the Test ID of Pre BUN and 191 is the Test ID of Treatment Time in Minutes and 189 is the Test ID of Pre Weight and 190 is Test ID of Post Weight, in PROLIS.

LDL (bad cholesterol) to HDL(good cholesterol) ratio is used to predict the chances of developing heart disease. LDL/HDL ratio should be above 0.3 and above 0.4 is ideal.

The iron saturation level measures iron binding and transportation in our body. A low saturation level indicates iron deficiency and a high level indicates excess iron in the blood. Some conditions such as chronic infections, anemia and cirrhosis can cause abnormal results.

**Calculate Iron Saturation – transferrin Saturation Formula**
