FECAL LACTOFERRIN

MERCY LAB CODE

LCTF

Mercy Medical Center - North Iowa Microbiology department performs a stool LACTOFERRIN, to determine the presence of fecal white cells in a stool sample. A fecal smear is no longer performed.

• Fresh specimen only. Collect fecal specimens in a clean, screw-topped container with no preservatives.
• Specimens should be submitted to Mercy lab REFRIGERATED (Frozen stool samples are also acceptable)
• Specimens should be submitted within 2 weeks of collection

• Due to Lactoferrin being present in breast milk, fecal samples from breast fed infants should not be used with this assay.
• Call Mercy Micro Lab (ext 8-7494) for further directions if testing on a breast fed infant is needed.

• Write in Fecal Lactoferrin LCTF on order form
• Send the specimen refrigerated (frozen is also acceptable, but not necessary) to Mercy Lab.
• Send within 2 weeks of collection

Negative, result indicates the absence of fecal leukocytes and intestinal inflammation.
