Should I attend my job interview despite the travel costs and blood test?

My job interview is on Tuesday, and I have to take a taxi there and walk 20min back. Then I have to spend on bus to go town because I need my bloods taken.

I have been off work for 4 years, and I need a job but its hard. I am 29.
