Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigators will seek to enroll 8 children ages 2-18 years already undergoing esophagogastroduodenoscopy (EGD). For the purposes of research, a peripheral blood specimen will be collected at the same time of peripheral intravenous (IV) placement, which is routinely performed for the purposes of sedation during endoscopy, thereby avoiding extra needle sticks. A urine sample will also be collected on the day of the EGD. These specimens will then be analyzed for plasma and urine metabolomics to evaluate for any derangements in EoE versus non-EoE subjects.
Risks to participants undergoing EGD are the same as they would be if they were not enrolled in the study as no additional biopsies will be taken. Risks associated with a blood draw are minimal and include some discomfort, such as lightheadedness, fainting, bruising, soreness, clotting and bleeding at the site of the needle stick, and in rare cases, infection. Collection of the urine specimen is by clean catch in only toilet-trained individuals.
This study should yield valuable information regarding plasma and urine metabolomics in EoE versus non-EoE subjects. Once this "discovery" data set is analyzed, future research could then focus specifically on those abnormal metabolites and seek to enroll many more subjects for a validation phase.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Pediatric patients undergoing EGD
Subjects ages 2-18 years undergoing upper endoscopy (EGD) will submit a blood and urine specimen for plasma and urine metabolomics profiling.
Plasma and urine metabolomics
Through the use of high-pressure liquid chromatography and mass spectrometry, quantitative measurements of targeted metabolites associated with amino acids, methylation, acetylation and the tricarboxylic acid (TCA) cycle will be analyzed on the blood and urine specimens.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Children with known EoE will only be enrolled if his/her biopsy on the day of specimen collection demonstrates ≥15 eosinophils (eos) per high power field (hpf).
Exclusion Criteria
2. Children with known EoE and biopsy demonstrating \<15 eos/hpf at the time of specimen collection.
3. Inability to provide a clean catch urine specimen (i.e. not toilet-trained).
