In nutritional status assessment, which sequence correctly orders the markers from highest to lowest as listed?

Explanation:
Think about how quickly each marker reflects changes in nutritional status. The speed of change depends on how long the protein stays in circulation, its turnover, and how it’s influenced by other factors. Prealbumin (transthyretin) has the shortest half-life, so its level responds fastest to recent nutrition changes. Fibronectin turns over more slowly than prealbumin but faster than albumin, placing it in the middle. Albumin has the longest half-life and is affected by many non-nutritional factors (hydration, inflammation, liver function), making it the least quick to reflect short-term changes. So, in order from most rapidly responsive to least, you get prealbumin, fibronectin, then albumin.
