LOINC Code 79411-5: Creatine transport protein Creatine uptake assay (Fibroblast) [Catalytic activity/Mass]

79411-5 is a LOINC code used to identify Creatine transport protein Creatine uptake assay (Fibroblast) [Catalytic activity/Mass] in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Creatine transport protein. It is commonly used with the system or sample type Fibroblasts.

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Creatine transport protein. It is commonly used with the system or sample type Fibroblasts.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Both
  • Method: Creatine uptake

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

  • Creatine transport protein [Enzymatic activity/mass] in Fibroblast by Creatine uptake assay
  • Creatine transport protein
  • Creatine uptake via the creatine transport protein is determined by measuring the incorporation of creatine into fibroblasts. Decreased levels are associated with mutations in the SLC6A8 gene, which encodes the creatine transporter protein. The defect is clinically manifest in muscles cells, leading to muscle weakness. Creatine uptake is effected in many cell types, including fibroblasts, which are easy to collect. Therefore fibroblasts can be used as indicators cells for the creatine uptake defect.
