Hi, MaryAnn! You’re so sweet for wanting to donate for your husband. From my understanding, platelets aren’t required to be type specific like red blood cells. So, theoretically, you could be a donor for your husband.
There is such a thing as Directed Donors, where you can specify the recipient. You’d have to contact a local blood center to see if you’re eligible to donate for your husband. There is criteria that has to be met before a person can donate blood…it applies to Directed Donors as well.

After the blood is collected it is separated into different blood products so your husband might use your platelets but the other components may be put into general distribution for other’s in need.

Or, you could simply donate blood at a local center. They’re always in need. And then when your husband requires platelets he’ll receive someone else’s but your donation would help several other people.

A platelet count of 125 is a little low, so that could explain your husband’s bruising. A ‘normal’ range for men is 135,000 and 317,000 platelets per microliter of blood. While his August check was just slightly below the minimum for the norm, platelets have a short life span 7-10 days, so it is possible that his level is lower than his dated test.

Did his hematologist mention a possible platelet transfusion in the future?
