A 24-hour urine sample is preferred for the 5-HIAA test because the level of the metabolite can vary during the day. For a 24-hour urine collection, all of the urine produced should be saved for a 24-hour period. It is best to keep the sample in a cool, dark place, such as a ...
After negative CT and octreotide scans, it was felt that the patient's 24 hour urine 5-HIAA test was falsely elevated due to dietary intake. She was instructed to avoid serotonin-rich foods prior to her repeat urine collection. The subsequent 24 hour urine test returned within normal limits....

Blood 5-hydroxyindole acetate (5-HIAA), urine 5-HIAA, and serotonin degradation metabolite levels were elevated at 1121 ng/ml (NR 57-230 ng/ml), 472 ng/ml (NR 1.8-6.1 ng/ml), and 86.9mg/13h (NR 1-6mg/24h), respectively, confirming the diagnosis of carcinoid syndrome. Metastatic Re...
Additionally spot urine samples were collected from 34 healthy children for control. 5-HIAA was detected from the urine samples in all children with high-performance liquid chromatography (HPLC) method. The results were analyzed with one way analysis of variance (ANOVA), post hoc Tukey HSD test ...
A cerium-based metal-organic tetrahedron for fluorescent recognition of 5-HIAA and its application in urine testUrine testTumor markerFluorescent sensorA cerium-based metal-organic tetrahedron including triphenylamine was applied to recognize the 5-hydroxyindole-3-acetic acid (5-HIAA), a kind of ...
Urine testTumor markerFluorescent sensorThe tetrahedron could encapsulate 5-HIAA through weak interaction and space stereo selectivity.The sensor exhibited a turn-on fluorescence response, and it has high sensitivity and good selectivity for 5-HIAA.The sensor is capable of detecting 5-HIAA in real ...
2) Diurnal variations of 5-HIAA levels in 3 hour urine fractions were the greatest in acute psychotics followed by organic psychotics, chronic schizophrenics and controls. Acute psychotics tended to stabilize with clinical improvement, but still were relatively unstable even in states of near ...
Additionally spot urine samples were collected from 34 healthy children for control. 5-HIAA was detected from the urine samples in all children with high-performance liquid chromatography (HPLC) method. The results were analyzed with one way analysis of variance (ANOVA), post hoc Tukey HSD test ...
The sensitivity of the test was 54.3% based on 7.4 渭mol/L as cut-off %-HIAA value. Conclusion Our study reports that 5-HIAA urine concentration is not a reliable diagnostic marker for the diagnosis of acute appendicitis.doi:10.1016/j.plabm.2020.e00198Leila Haji Maghsoudi...
