Brief Answer:
No need to worry about

Detailed Answer:
Membranous nephropathy (MN) is a genetically mediated disease with few antibodies make a complex and get deposited below filtering membrane in kidneys. The filtering membrane becomes thick and pores get wide opened and hence there is a free passage of protein in the urine leading to losses as the protein is an abnormal substance for urine tract once filtered, it gets into the adjacent tubules and damages the structure and thus kidney damage sets in kidneys.

It seems the MN is simple with you as you responded well with steroids before and the relapse is taking place after several years now. Almost 30 percent resolve without therapy and 40 percent respond to therapy and only remaining few gradually progress to kidney failure. You have few good points with you that you responded well before and there is a late relapse. But men have a bit high tendency to kidney damage compared to women.

Still, there appears to be a dim old form of MN for you. You can get back once you get the reports. Other blood reports mentioned by you are all normal including ESR and we don't need to read too much about simple reports which are of no major clinical significance or consequences.
