RESUMO
Consumption of commercial soft drinks or tea has increased in over recent years. In many case, these drinks contains large amount of ascorbic acid as an antioxidant. We examined the influence of ascorbic acid to the result of urine occult blood and sugar tests with urinalysis reagent strips. Three subjects took 3 brands of soft drinks (P, C, B) in 3 different days once in the morning. Other 3 subjects took 4 brands of green tea in 4 different days 4 times in a day. After 2 hours of first administration, urine specimen were collected every hour for 8-10 hours. Constant amount of hemoglobin or sugar was added in urine specimen and the reflectance was measured with AX-4280. As a results, urine ascorbic acid induced false negative results in both occult blood and sugar tests in all groups. These results indicate the necessity of patient education about commercial soft drinks or green tea consumption on the previous night and the day of the urinalysis.

In the nutrition support team (NST), medical technologists take a very important role in carrying out nutrition screening, nutrition assessment and nutrition monitoring. Medical technologists can look at the laboratory data of patients earlier than other NST staff. Using this advantage, the medical technologists can contribute to the NST. In addition, medical technologists join ward rounds together with other NST staff on a weekly basis. After discussion with all NST staff, medical technologists make a report on the nutrition assessment of patients and then sign their names to the report. The NST is a representative of medical treatment teams. All NST members should have equal levels of understanding of nutrition therapy. Therefore, medical technologists should not only look at the laboratory data of the patients, but also manage the patients through nutrition assessment and nutrition monitoring.
