SEROTONIN

LAB121

 

Collect

Serum separator tube.

Patient Preparation

Abstain from medications for 72 hours prior to collection.

Specimen Preparation

Spin and separate within one hour. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.3 mL)

Unacceptable Conditions

Specimens other than serum. Non-frozen specimens.

Storage/Transport Temperature

Frozen.

Stability (from collection to initiation)

After separation from cells: Ambient: Unacceptable; Refrigerated: 24 hours; Frozen: 1 month

Notes

Medications that may affect serotonin concentrations include lithium, MAO inhibitors, methyldopa, morphine, and reserpine.  In general, foods that contain serotonin do not interfere significantly.  Slight increases may be seen in acute intestinal obstruction, acute MI, cystic fibrosis, dumping syndromes, and nontropical sprue.  Metastasizing abdominal carcinoid tumors often show serotonin concentrations greater than 400 ng/mL.

In general, EDTA whole blood (as compared to serum) preserved with ascorbic acid will give values most representative of blood concentrations. Most (95 percent) of blood serotonin is found in platelets. Refer to Serotonin, Whole Blood (ARUP test code 0080395).

Performed

Sun, Tue-Fri

Methodology

Quantitative High Performance Liquid Chromatography

Reported

1-5 days

Synonyms

  • 5-Hydroxytryptamine, Serum

  • LAB121

Ordering Recommendations

Preferred serotonin test when diagnosing carcinoid tumors is Serotonin, Whole Blood (0080395).

Reference Interval

50-220 ng/mL
