matching

 [mach´ing]
1. comparison and selection of objects having similar or identical characteristics.
2. the selection of compatible donors and recipients for transfusion or transplantation. See also typing.
3. the selection of subjects for clinical trials or other studies so that the different groups being compared are similar in specified characteristics, e.g., age, sex, or race, in order to reduce bias caused by comparison of dissimilar groups. Matching may be on an individual (matched pairs) or a group-wide basis.
cross matching crossmatching.

match·ing

(match'ing),
The process of making a study group and a comparison group in an epidemiologic study comparable with respect to extraneous or confounding factors such as age, gender, and weight.

matching

EBM
The grouping of individuals or groups by researchers based on particular variables thought to be important (such as gender or age). In a case-control study, if the controls are chosen because of particular similarities to the people who are in the case group, the cases and controls are said to be “matched”.

Social medicine
The attempt to select adoptive parents similar to the child being adopted, as in appearance, interests, intelligence, personality or other traits, so as to achieve the best outcome for the adoption.

matching

Clinical trials A process by which a study group and comparison group are 'equalized' with respect to factors viewed as extraneous to the study's central questions, that might interfere with interpreting data on study completion. See Case-control study. Cf Match.

matching

comparison for the purpose of selecting objects having similar or identical characteristics.

blood matching
see cross-matching (below).
control matching
see matched study.
cross-matching
determination of the compatibility of the blood or tissue of a donor and that of a recipient before transfusion by placing erythrocytes or leukocytes of the donor in the recipient's serum and erythrocytes or leukocytes of the recipient in the donor's serum. Absence of agglutination, hemolysis and cytotoxicity indicates that the two blood or tissue samples belong to the same group and are compatible.

Patient discussion about matching

Q. Hi members, after I notice that our symptoms match those of fibromyalgia. Hi members, after I notice that our symptoms match those of fibromyalgia, do we have to live with it and simply manage it for the rest of our life or try some luck with food and meds? Thanks.

A. If you could have given a particular age details then it could have been easy to analyze. This condition is relatively new, yet it's appearing in epidemic numbers. Dr. Whiting (an orthomolecular nutritionist), finds in his work with people suffering with this that they are all very toxic. When their systems have been properly detoxified their symptoms will disappear. His personal feeling is that this is a condition of hyper-toxicity and manifests itself in people who are unable to physically cope with the overload of toxins in their system.
