There are different ways to measure oxytocin levels.
The best and most accurate is to measure the levels of oxytocin in cerebrospinal fluid, which bathes the brain. This is a very invasive procedure. Collecting CSF requires an invasive lumbar puncture procedure, in which a needle is inserted into the space around the spine.
Another method is to test oxytocin levels in the blood. Scientist were unsure how well these measurements reflected the hormone’s levels in the central nervous system. The new study shows that, although oxytocin levels are consistently lower in blood than in CSF, the levels of the hormone in the two are linked. So blood tests are an accurate means of measuring oxytocin. Source:
Oxytocin levels in blood, cerebrospinal fluid are linked, study findsOther methods such as measuring oxytocin in urine and in saliva appear to be much less reliable.
But another recent discovery in blood analysis has occurred. They found that most of the oxytocin in blood is essentially invisible (not being measured) because it is bound to proteins. This is about a 100 to 1 ration. Therefore to get an exact measurement in blood requires a robust nano liquid chromatography-mass spectrometry. So very accurate test still may be a ways off. Source:
