Harvest - S5-E3

Question: Why does Mrs Perez tell Catherine that they couldn't find a marrow donor for Daniel because he's mixed race? I thought it didn't matter what race you are when it came to donating organs or blood, as long as the blood types match or were compatible.

Answer: What is often called bone marrow transplants is the transplant of hematopoietic stem cell. Instead of blood type match, patients need to be an HLA match (human leukocyte antigen). There's a lower percentage of matching one's HLA type with a random person than blood type. When it comes to matching human HLA types, a person's ethnic background is important in finding a match because the HLA markers used in matching are inherited, and some ethnic groups have more complex tissue types than others. A person's best chance of finding a donor may be with someone of the same ethnic background, meaning someone on the registry would have to be of mixed race as well. At the time, the total number of multiple race donors in the registry was very low (I don't have the figures for 2004, but in 2014 there were less than 500,000 multiple race donors).

Too Tough to Die - S1-E16

Character mistake: Seven minutes into the show, Sarah Sidle is about to do an internal sexual assault exam/kit on an unconscious victim in the hospital, Sarah picks up a metal speculum and says aloud to the victim (in a presumed moment of empathy), that she "never really liked this part of my yearly exam. These things are always freezing" referring to the speculum in her hands. She then brings a speculum to her mouth and begins to blow open-mouthed on it two times, forcing her hot breath on it to warm it. She then begins to insert it into the victim as the scene cuts away. This is pure stupidity, as no trained CSI would ever contaminate the tool like this. Sarah just added her own DNA to the speculum via her breath so any saliva or body fluids are now on the speculum what she is about to use on this patient, who is now also exposed to any STDs from Sarah.

Sounds of Silence - S1-E20

Trivia: For those who don't (or can't) read American Sign Language, at the end of the episode, Grissom says to Dr. Gilbet is that his mother lost her hearing when she was eight years old. He once asked her what is it like to be deaf, and she told Grissom (who loved to swim) that it was like being underwater. She also taught him that being deaf does not make one inferior to others. Dr. Gilbert then replies that she teaches her students the same lesson.
