Practical Physiology 26.3.09Pregnancy test. BMR. BMI.
In pregnancy test, we're searching for human chorionic gonadotropin(hCG). hCG is formed by syncitiotrophoblast of the blastocele. hCG is found in the blood 6 days after contraception. Appearance of hCG in urine can be detected 14 days after contraception. Pregnancy test can be performed 1 week after contraception, or 1 week before the expected date of the next mens. Agglutination of urine or blood sample marks positive pregnancy test.
BMR or basal metabolic rate, are calculated 12 hours after the last meal. Two methods are use to calculate the value, which are direct or indirect. But people nowadays didnt use the direct method anymore as it is quite silly and is not very accurate.
In metabolic rate, they found that 4.8 calories are produced per liter oxygen consumed. BMR equals metabolic rate divides total body surface area(almk,xdpt recall,sile check blk formula). Value of the total body surface area can be taken from the graph on the second last page of physiology practical book, 2nd year of course. Normal BMR value is 40 + 15%. (getting more dizzy)
Meanwhile, BMI (body mass index) is calculated by using a special gadget, named...dun know.. Joystick-like structure, first we need to enter our details, concerning our height, weight, age, and gender. Outstretch our hands while holding it, and push the button start. It will tell us upon our fat percentage, and our BMI also. Average fat percentage among men is about 25% while in women is about 35%.
P/s: Dr. Heba said that men have less fat compared to women. This is because they are more muscular. But Malaysian men are so thin, no fat, and yet no muscles too! (LOL) While Malaysian women are also thin, no fat also (but most of our reading shows fat percentage more than 35%!!)
-a kind of recall method-
kalo slh btolkn~
