Part Descriptions
LP15558-7 Estriol
Estriol (also oestriol) is one of the three main estrogens produced in humans. It is only produced in large amounts during pregnancy as it is made by the placenta. Levels of estriol in non-pregnant women do not change much after menopause, and levels are not significantly different from those in men. Estriol levels can be a good indicator of the health of the fetus. DHEA is produced by the adrenal cortex of the fetus, this is converted to estriol by the placenta. Low levels during pregnancy may indicate a problem with the development in the child.

LP32035-5 Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
