Narrative: Fume event. Entire crew on jetway. Jetway broken. Aircraft with ground crew member in flight deck. APU on packs on all doors shut. Once door opened I entered aircraft went into flight deck and smelled the dirty mold sock smell and got off jet. Fumes started to enter jetway most of us left jetway. Fumes caused eye irritation and sore throat at time of this writing.  Maintenance tried to get the Captain and First Officer to do engine run ups after this incident.Ground crew who was in flight deck during tow most likely did not have training in the dangers of this type of fumes. I spoke directly to the station manager about how dangerous fumes are and how long [operator] was exposed. [Manager] said [operators] could not [be forced to] get blood tested. The ground crew members were exposed for over 10 minutes that I am aware. I am sure it was more like 10 to 20 minutes.I reviewed the QRH checklist for smoke/fumes. It needs [to be] improved. I suggest [company] look at what [other carrier] have done with their checklist and procedures. I have heard their mechanics are required to wear protection for engine runs etc.; after this type of event. [Company] maintenance should not be requesting pilots to trouble shoot with no protection after fume event. They asked us to return to jet and do engine run ups.


Second narrative: Plane was brought from the hardstand to gate. All crew was on jetbridge waiting to get on plane. The plane door was open and the FO (First Officer) and I entered the plane. He went into cockpit and I was in 1st class galley. I went to put my luggage away and told FO that the plane smelled awful. He agreed and we both got off. I got FA's [Flight Attendants] and we went halfway up the jetbridge and then the smell started coming up the jetbridge. We then went into the terminal. I called OPS and Crew Tracking. Paramedics checked us out and we deadheaded to ZZZ1 and we called [doctor] and were sent to [clinic] in ZZZ1 to be looked at.If you are involved in a fume event; the 1st thing once you call and report it; they should advise you to immediately step outside for fresh air. The doctor told us we need to do that. Second; it should be mandatory to immediately have blood drawn and tested for CO poisoning. We were under the impression that they would do that in ZZZ1. By the time we got there; it was too late to be tested.


Synopsis: Air Carrier First Officer and Flight Attendant reported a fumes event shortly after boarding the aircraft for pre-flight duties. First Officer reported experiencing health issues.
