For identification purposes the carbonyl and adjacent alcohol functions will form phenylhydrazine derivatives known as osazones, which give characteristic melting points and exhibit definite crystalline structure. It should be noted that glucose , fructose and mannose yield the same osazone since the difference in structure and configuration about carbon atoms 1 and 2 are abolished.
it is a reducing sugar.
Before answering your question, do you produce large amount of urine (polyuria)? LOW Specific Gravity test (1.003-1.009 [I think]) means that you have low amount of particles inside your urine. It is clinical significance serious, it may indicate type I diabetes. (you also may have polyuria) If it is just normal, you just drinking a lot of water (you also may have polyuria)
Clinical study design is the formulation of trials and experiments in medical and epidemiological research. Many of the considerations here are shared under the more general topic of design of experiments but there can be others, in particular related to patient confidentiality and ethics.
You test a hypothesis after you form it. But lets go over the scientific method anyway. You start with a situation, then you come up with a question, then a hypothesis: there are two kinds of hypothesis, null and alternate, null means that the results dictate that the treatment shows no Significance, where alternate shows that the groups have difference, which is significance. You test the hypothesis in an experiment, and there are many different tests that you can apply to the DATA you collect.
A clinical approach involves the use of empirical information and treament.
Clinical Case Studies was created in 2002.
Reagents of Osazone test are 1. Phenylhydrazine mixture consisting of phenyl-hydrazine and anhydrous sodium citrate 2. Orignal solution containing a carbohydrate
The phenylhydrazine test is also known as the Osazone test. The phenylhydrazine test is used for reducing the amounts of carbohydrates, momosacchstides, and disaccharides.
osazone test is a carbohydrate specific reaction in which carbs react with phenylhydrazine to form osazones i.e. crystals of specific shape. thus the test confirms the presence of a particular sugar.Eg:for sucrose one gets a mixture of glucosazone and fructosazone on the basis of components of sucrose.
clinical importance of pleural recess
There is a great clinical significance of calcification. Calcification can lead to things like kidney stones that are very painful.
A clinical correlation from a stress test involves interpreting the test results in conjunction with the patient's symptoms, medical history, and other diagnostic tests to arrive at a diagnosis or treatment plan. It helps the healthcare provider determine the significance of abnormal findings on the stress test in relation to the patient's overall health condition.

D-erythrose and D-threose both yield the same osazone. Likewise, L-erythrose and L-threose yield the same osazone.
Glucose, Fructose and Mannose give the same osazone because these sugars have the same configuration of carbons 3, 4, 5 and 6. osazone formation only affects carbons 1 and 2.
Isolated Widal test reading does not have much clinical significance. Rising titre of Widal test done one week apart, in a febrile patient, indicates typhoid fever. You can have such rising titre of Widal test in healthy patient, after dose of typhoid vaccine.
