Can I use "pass through" instead of "pass up" here?
No, to "pass through" has a different meaning than to "pass up". To "pass up" here means to decline, reject or fail to accept something. To "pass through" on the other hand means to walk through or move through something. Ex: Don't pass up this opportunity! Ex: I can't believe she passed up the chance to go skydiving.
