Results of Diagnostic Tests

Skin tests with various tetracycline compounds in different concentrations have been performed by many clinicians. Unfortunately, non-sensitizing conjugates of tetracyclines with small polypeptide carriers are not available. This is mainly due to our inadequate knowledge of the haptenic determinants responsible for tetracycline allergies. Therefore no effective diagnostic skin tests exist at present. 

For routine skin testing, tetracycline solutions in concentrations of 0.05-0.5 mg/ml for scratch and intracutaneous tests and 10 mg/ml for patch tests have been used. Positive results were obtained in some cases of highly sensitized patients. Zelger and Seidl (1969) obtained a positive scratch test with oxytetracycline in a highly sensitized nurse. Fellner and Baer (1966) reported a positive skin test of the immediate type in a penicillin- and tetracycline-sensitive patient using intracutaneous application of tetracycline. Patch tests gave positive reactions more readily, especially among medical staff and factory workers (Korossy 1976). 

To establish IgE-mediated allergies to tetracyclines, Prausnitz-Kiistner tests were performed and positive results were obtained in some cases (Fellner and Baer 1966 Lochmannova et al. 1970).

The selection of foods to eliminate should be based on a variety of items, including history of illness, age of patient, results of diagnostic tests, epidemiological considerations, adherence to the diet, and elimination of additional triggers which may cause symptoms (Sampson, 1999a Sicherer and Sampson, 1999). 

Optometrists have a similar duty to discuss the results of diagnostic tests with patients and to advise patients of the availability of further testing to rule out the presence of disease. Ambiguous or suspicious findings should be resolved, and if patients do not return for recall appointments or do not wish to undergo further evaluation, these facts should be documented in the patient record. 

Results of Diagnostic Testing Showed a INSA [a cancer marker] of 35.5, Hemoglobin of 9.7, Hematocrit of 28.4 with RBC s of 3.14 and ESR at 140 plus, Serum Ferratin of 200 and Bone Imaging equivalent to that of an average 83-year-old male. [All of these lab results are abnormal.]... 

Results of Diagnostic Testing On 12/7/87, revealed liver dysfunction, also Hypoglycemia with Hypoadrenocorticism. On 8/ 4/89, Anti-Candida blood test revealed an IGG of 239, IGA of 184, IGM of 118 [abnormal].
