I had a blood test (Western Blot), to check for Lyme Disease. The results look strange (0.45). This doesn't look like the result of any WB test I have?

Probably not Lyme. Your Western Blot would need to be above 5 for a conclusive confirmation of Lyme disease. Unless you also had known tick bite, low-grade fever, "erythema migrants", you probably had a viral illness that should resolve on its own. Do discuss this with your primary medical provider or specialist if symptoms persist. .

Will the regular blood test and western blot test for Lyme disease rule out someone having it?

It is a good test.. Enzyme-linked immunassay is a sreening test which if positive will be confirmed with a western-blot (=standard of testing). Although not absolutely 100%, a negative western blot is a good bet that there is no lyme at the time of testing. Early disease/infection may have negative test, thus recommended retesting in about 3 wks. Lyme dna testing is better, but more expensive. Consult doc..Good luck. Read more...
Appropriate context. Tests such as elisa or western blots are not enough to diagnose lyme. The appropriate clinical context is also needed. If the patient has never been to environments where he or she can be bitten by ticks that cause lyme (eg. Ixodes scapularis or ixodes pacifica), then testing is not really necessary. A positive result withotu exposure may represent a false (+) result or crossreactivity. Read more...

I recently had a blood test, it showed a potential false pos of hep b, but is there a link between Lyme disease and hepatitis?

NO. Lyme does not cause hepatitis. The clinical presentation of the 2 with aches, pains, fatigue, stiffness, weakness can overlap and be confusing. Lyme needs antibiotics hepatitis does not. See your doctor. Read more...

Is it common for a blood test to miss Lyme disease? Also can Lyme disease lead to weight loss?

Yes. Are difficult to detect for lyme disease unless it is an acute infection with a classic target lesion fever and malaise and the chronic state you have to use serology this is very nonspecific and sometimes it is difficult to detect the lymes antibody. Lymes disease can lead to weight loss especially the chronic phase. Read more...
Yes to both. It is fairly common for lab tests for lyme disease to be a false negative. The cdc criteria for a positive test is so strict that it might miss up to 50% of patients who have lyme disease. Read more...
