I was wondering about the sensitivity/accuracy of liver blood tests. I have always been very health conscious, as a lot of serious medical issues run in my family. I always go to my yearly doctor visits where they order routine blood work for blood counts, organ function, thyroid, etc. I always look at my results and what the numbers mean, etc. Overall, I have always been generally healthy and I try to take good care of myself. I do drink alcohol and have done so for about 15 years - some of which included moderate to heavy social drinking in college, etc. After having kids, I would say it has been just light to moderate drinking, but I probably have exceeded the 7 drinks a week recommended limit at times. I have recently been reading that liver blood work can remain normal in some cases even when liver disease is present. My liver blood work has always been well within normal ranges, which has given me comfort, but after reading that normal tests may not always indicate a healthy liver, it got me wondering what other kind of preventive screening can be done to detect liver issues in early stages. I did have an abdominal ultrasound done about 2.5 years ago to check on my gallbladder after having a baby and that was also completely normal for all organs including liver. I obviously know that diet, lifestyle, etc. plays a big role. But is blood work even able to detect small amounts of disfunction? How sensitive are these tests? Is it common to have normal blood work in early stages of liver disease? Just trying to educate myself on this and stay on top of preventative care, etc.
