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 Testosterone/Cortisol. It is commonly used with the system or sample type Ser/Plas.

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

What it does not mean

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

Key facts

• Testosterone/Cortisol [Molar ratio] in Serum or Plasma
• Testosterone/Cortisol
• The testosterone/cortisol ratio (T/C ratio) is an indicator of recovery from exercise or over-training, and there is some suggestion in the literature of an association between an elevated T/C ratio and aggressive behavior. Testosterone is released following a series of a hormonal processes that begin in the pituitary gland, and its effects include increasing muscle protein synthesis and reducing the catabolic effects of cortisol. Cortisol is released by the adrenal gland under conditions of high physical and mental stress and high temperature, and its effects include reducing growth hormone and testosterone output, reducing muscle and increasing abdominal fat, and impairing immunity, learning and memory.
