What usually happens next
Kidney disease at this level only counts if there's another sign, most often albumin in the urine.
If you have diabetes or high blood pressure, a yearly urine ACR is the other half of the check.
When an eGFR can read wrong
Most eGFRs are worked out from creatinine, which comes from muscle. A lot of muscle, creatine supplements, a big meat meal before the test or being dehydrated can make the eGFR read lower than your kidneys really are; very little muscle can make it read higher. A cystatin C based eGFR is the usual way to check.

Questions
Is an eGFR of 91 mL/min/1.73m² normal?
An eGFR of 91 mL/min/1.73m² is 90 or above, the range KDIGO calls normal or high (stage G1). The usual range is 90 or above (it drifts down with age).
Is an eGFR of 91 mL/min/1.73m² normal for my age?
eGFR falls slowly with age, so a value in the 60s or 70s is common in healthy older adults. What matters is whether it stays under 60 for more than 3 months, or comes with albumin in the urine.
Can an eGFR of 91 mL/min/1.73m² improve?
It can move: dehydration, a big protein meal or a hard workout before the test lowers it, and a repeat test when well hydrated often reads higher.
