Dr called said blood tests were normal Rcvd lab results MCH is low & total Bilirubin @1.9. All other results are in normal range. What does this mean?

Dr called said blood tests were normal Rcvd lab results MCH is low & total Bilirubin @1.9. All other results are in normal range. What does this mean?

Maybe Gilbert's?: It is a familial (autosomal dominant), common (2-5% of people), unconjugated hyperbilirubinemia (blood bilirubin measures 1-5mg/dl), not due to breakdown of blood. It is associated with reduced enzyme levels of udp glycuronyl transferase, that results in jaundice when patients fast or suffer an infection. It does not shorten life or raise insurance rates, but may predispose to tylenol (acetaminophen) toxicity. ...Read more

Test result for Alk Phosphatase below standard range. Others (total bilirubin, bun, albumin, total protein) also low. What could this mean? Next step?

See your clinician: There may be nothing "wrong" with you. Note that no test is perfectly accurate. Also, if you're at very low risk for a disease, an abnormal result is less likely to be true. You need to sit down with a clinician to review your tests in light of your overall personal & family medical history, physical findings, & health goals. Next steps include further tests, & watch & wait. Hope that helps. ...Read more
