Just did a heart catherazation and my hgb is 10.8 pa and fa is11.5 what does that mean?

Details...: Hgb is a measure of your blood count; >12.5 is nl:you're anemic. Pa mean pressure of 10.8 is normal. Fa is not a standard abbreviation: i suspect you mean ra. Normal is <8 thus you're a little high. Impossible to comment further without more context.

Statistical variatio: It sounds like they measured your HGB from both your pulmonary artery and femoral artery, likely as part of a fick cardiac output determination. This is likely normal statistical variation. The important numbers are the oxygen content difference between the arterial and venous sites, which goes into the calculation for cardiac output.
