Answer: eGFR stands for “estimated glomerular filtration rate”. The eGFR test is done to measure the levels of kidney function. It is usually calculated from the results of creatinine test, your age, body size and gender. In adults, the normal eGFR number is considered to be 60 or more.

14. What is Albumin in blood test ?

Answer: Albumin is a protein made in the Liver. An albumin test is done to measure the amount of albumin in blood. Low albumin level may be a sign of Liver or Kidney diseases. High levels may indicates the sign of dehydration. The normal albumin levels in an adult’s blood range from 3.5 to 5.5 grams per deciliter (g/dL).

15. What is PSA in a blood test ?

Answer: PSA stands for “prostate-specific antigen”. It is a protein made only by the Prostate gland. PSA test is a blood test done to measure the level of prostate-specific antigen in the blood to detect prostate cancer. There is no specific normal or abnormal level of PSA in the blood but usually 0 to 2.5 ng/mL is considered to be safe.

16. What is Bilirubin in blood test ?

Answer: Bilirubin is a yellowish pigment made during the normal breakdown of Red Blood Cells(RBC). It ultimately passes through the liver and excreted out of the body. A bilirubin test is done to measure the amount of bilirubin in the blood. For adults over 18, normal level is 1.2 milligrams per deciliter (mg/dL) and for below 18, the normal level will be 1 mg/dl.

17. What is Glucose in blood test ?

Answer: Glucose is a type of sugar and acts as the body’s main source of energy. A blood glucose test is done to measure the levels of glucose in your body.
