Abstract
Some studies have shown a negative association between age and serum albumin. Several of these studies included older people with known disease. Disease may reduce albumin in any age group. Other studies have shown no association between age and albumin. To investigate the association of age and albumin, albumin levels were determined in 241 apparently healthy subjects aged 55 to 101. A small but consistent negative regression slope of about 4% per decade was found for those aged over 70. Because the relationship to age was small, the findings of hypoalbuminemia in an elderly patient generally should be attributed to disease rather than age alone.
