Summary Introduction
To analyze:
Whether switching from phase 1 to phase 2, that is, nonorganic to organic, lowers the amount of pesticides secreted in the urine of the children or not in the following experiment.
Levels of metabolites (breakdown products) of malathion and chlorpyrifos in the urine of children taking part in a study of effects of an organic diet:
Malathion metabolite Chlorpyrifos metabolite |
Study phase | No. of samples | Mean (µg/L) | Maximum (µg/L) | Mean (µg/L) | Maximum (µg/L) |
Nonorganic | 87 | 2.9 | 96.5 | 7.2 | 31.1 |
Organic | 116 | 0.3 | 7.4 | 1.7 | 17.1 |
Nonorganic | 156 | 4.4 | 263.1 | 5.8 | 25.3 |
Introduction:
Organic foods are produced using methods that meet the standards of the organic farming. The organic food tends to limit the accumulation of the toxic compounds, which one might be consuming along with the nonorganic food substances.

A urinalysis is a test that examines physical, chemical and microscopic aspects of urine. Examining urinary fluid can reveal much about the functioning of the body, as changes from the normal characteristics or appearance may reflect specific diseases. Currently, commercially-available chemical reagent sticks can be used to detect substances in urine. Of the following, which are substances that reagent sticks can test for?
a.
Substances produced by the body, and naturally found in urine.
b.
Substances produced by the body, but not usually present in urine.
c.
Substances not normally found in the body.
d.
a. and c. only
e.
a., b., and c.
A patient with a rash gets a combination prescription from his physician to help alleviate the itching and moisturize the skin. The prescription is for 60% ingredient A and 40% of ingredient B for a total of 155 g (in a single tube). The patient has 3 refills on this prescription and wants to pick up the entire amount today: how much in g is that? Hint: 3 refills includes an original prescription so the total amount to be picked up is 4 tubes)
What are the commonly used methods for the determination of urea, uric acid, creatinine, creatine,
and ammonia in plasma and urine. What interferences might affect the interpretation of the results of these assays and how can they be mitigated? Identify sources of error and variability in these methods and describe the effects on the clinical utility of the laboratory measurements.
