I have slightly elevated bilirubin, my urine showed trace amounts of blood, and I have muehrcke's nails. How worried should I be?

Concerning. Muehrcke's lines of the nails are indicative of decrease protein synthesis. It is alo called leukonychia striata. With concomitant elevated bilirubin and hemturia, this can indicate conditions relating to liver or biliary conditions, metabolic stress, nephrotic condition, other systemic disease or malnutrition.
Stop worrying. Nondepressed white lines in the nails in a person who doesn't feel sick mean nothing. A slight elevation in bilirubin can be from gilbert's non-disease, from a deep bruise (happened to me), or from something else. Trace blood without visible red cells in the urine can be just from exercising but needs follow-up. Let your physician sort this out and be compliant.
