differential diagnosis
the differences between diseases in terms of clinical signs and epidemiological parameters; used as a basis for selecting as a diagnosis the one with the best fit to those seen in the subject.
differential leukocyte count

differential milk cell counts
count of cells in a milk sample including individual counts of somatic cells and individual leukocyte types.
differential thromboplastin time
used in differentiating the cause of hemophilia. Reagents containing either factor VIII or factor IX are added in the partial thromboplastin time test to demonstrate which factor corrects the prolonged clotting time.

Patient discussion about differential

Q. How do you differentiate between fluorosis and caries? Both appear as white spots on the teeth, so clinically how do you differentiate between them? I know it has something to do with their appearance while wet and dry, but I am not sure what? please help me I can't find this in any book.

A. Only mild fluorosis is seen as white stop lesion on the tooth. It usually comes with brown spots. Look for them. Another method is trying to stick a dental explorer into it (not the Microsoft one- it’ll only be a portal for viruses..) and because caries is demineralized area it will feel kind of sticky. But I wouldn’t do that…it can harm the teeth. Another way is by an x ray. Fluorosis- you will see it as a whiter spot. Caries- a more translucent spot.

Q. Differentiate Wheezing & Asthma My sister who is 29 years old is suffering from wheezing for the past 7 years. Its not a genetic problem. Some times she uses inhaler for temporary recovery. She tried English medicine, homeo and other treatments. Is it an Asthma? I find very difficult in seeing her struggle when she find hard to breathe. Please help to make her free out of this struggle.

A. i see what scares you...it's frustrating to see your loved ones suffer and you cannot help. if she is has an inhaler- that mean she has been to the Dr. and he prescribed her some kind of medicine. without giving a diagnose first...?

Q. how can i differentiate between normal stomach ache and an Appendicitis? I've been having a strange sharp pain in my stomach lately and a friend of mine told me it could be Appendicitis.

A. When you have Appendicitis, there should be a sharp pain on the right lower Abdomen. but you mustn't forget that Appendicitis is an inflammation. which means you'll have a fever some time in the near future, and it always get worse. not like other Abdominal pains. you'll vomit probably. i had my Appendix removed 2 years ago. don't worry, it's not too bad ;).
