If fingerprints remain they must be collected with an adequate substance, as ninhydrin.
Mercury must be collected with a piece of copper dipped before in mercury to form an amalgam on the surface.
While FDA guidelines do allow compensation for donation of blood components intended for transfusion, there are currently no blood centers in the U.S. that pay donors. Since any blood products collected from such donors must be labeled as "Paid Donor", hospital transfusion services are reluctant to accept these units. Aside from a few small hospital-based collection centers, there has not been payment for blood donations since the early 1970's. You may, however, become a compensated source plasma donor. Plasma is collected by apheresis technology at local plasma centers. The FDA requires source plasma donors to have a permanent address within a specified distance from the collection site. Search your local yellow pages for "plasma" or "blood" for the nearest plasma center.

Cord blood banks collect blood from the fetal end of umbilical cords immediately after a baby is born. In order to ensure the preservation of the umbilical cord blood, at least 75mL must be collected and tested for various diseases.

Current FDA guidelines allow a maximum of 10.5 ml/kilogram body weight of whole blood to be collected every eight weeks. The majority of blood collection facilities use 500 ml whole blood bags, with an additional 50 ml (10%) allowed to be drawn for mandated screening tests. This volume equates with a lower body weight for blood donation of 110 lbs or more (with acceptable hematocrit/hemoglobin levels). Double red cell donation by apheresis technology may collect 500-550 ml of red cells at a single donation IF the donor meets body mass and hematocrit eligibility criteria. Double red cell donors must wait 112 days before their next blood donation attempt (any type).

Studies have indicated that volunteer whole blood donors begin experiencing adverse reactions (weakness, nausea, vomiting, syncope, etc) when blood loss exceeds 15% of total blood volume. As such, FDA recommendations, listed below, are in place to assure that less than 15% is collected from volunteer blood donors.Current FDA guidelines allow a maximum of 10.5 ml/kilogram body weight of whole blood to be collected every eight weeks.

While the FDA does allow blood collection centers to compensate for blood donation, there are currently no centers in the U.S. that pay the donor. Blood components collected from such donors must be labeled "Paid Donor" instead of "volunteer donor". As such, regional hospital transfusion services are reluctant to accept such products.
Platelets don't carry any specific anti-body or antigen that would need to be matched up as the whole blood does as to not cause coagulation
Presumably to prevent the gas from escaping.
