Estimation of Creatinine Clearance from Serum Creatinine by Prediction Equations

One can estimate GFR from age, sex, body weight, and serum creatinine value of a person from the following formula (Cockcroft and Gault):     Creatinine clearance in ml/min = (140 - Age in years) × (Body weight in kg)                     …

CLEARANCE TESTS TO MEASURE GLOMERULAR FILTRATION RATE (GFR)

Glomerular filtration rate refers to the rate in ml/min at which a substance is cleared from the circulation by the glomeruli. The ability of the glomeruli to filter a substance from the blood is assessed by clearance studies. If a substance is not bound to protein in plasma, is completely…

ROLE OF LABORATORY TESTS IN DIABETES MELLITUS

Diabetes mellitus (DM) is a metabolic group of disorders characterized by persistent hyperglycemia due to deficiency and/or diminished effectiveness of insulin. There are derangements of carbohydrate, protein, and fat metabolism due to failure of insulin action on target cells.

PREGNANCY TESTS

Pregnancy tests detect human chorionic gonadotropin (hCG) in serum or urine. Although pregnancy is the most common reason for ordering the test for hCG, measurement of hCG is also indicated in other conditions as shown in Box 836.1. Human chorionic gonadotropin is a glycoprotein hormone produced by placenta that circulates…

SEMEN ANALYSIS FOR INVESTIGATION OF INFERTILITY

Semen (or seminal fluid) is a fluid that is emitted from the male genital tract and contains sperms that are capable of fertilizing female ova. Structures involved in production of semen are: Testes: Male gametes or spermatozoa (sperms) are produced by testes; constitute 2-5% of semen volume. Epididymis: After emerging…

SPERM FUNCTION TESTS OR FUNCTIONAL ASSAYS

These tests are available only in specialized andrology laboratories. The tests are not standardized thus making interpretation difficult. If used singly, a sperm function test may not be helpful in fertility assessment. They are more predictive if used in combination.   Postcoital (Sims-Huhner) Test   This is the examination of…

IMMUNOLOGIC ANALYSIS OF SEMEN FOR INVESTIGATION OF INFERTILITY

ANTISPERM ANTIBODIES The role of antisperm antibodies in causation of male infertility is controversial. The immunological tests done on seminal fluid include mixed antiglobulin reaction (MAR test) and immunobead test. The antibodies against sperms immobilize or kill them, thus preventing their passage through the cervix to the ovum. The antibodies…

BIOCHEMICAL ANALYSIS OF SEMEN FOR INVESTIGATION OF INFERTILITY

Biochemical markers (Table 831.1) can be measured in semen to test the secretions of accessory structures. These include fructose (seminal vesicles), zinc, citric acid or acid phosphatase (prostate), and α-glucosidase or carnitine (epididymis).   Table 831.1 Biochemical variables of semen analysis (World Helath Organization, 1992) 1. Total fructose (seminal vesicle…
