Health obsession. For example, obsessively checking one's self or one's children for a disease to feel safe.
Having a hard time using something unless you have a back up. For example, buying 2 of the same book--one to highlight and the other which can "stay new".
Need for perfection.
Gambling compulsively.
Tourettes -
Tugging at clothes. Not letting something touch your skin.
Workaholic - can't stop and smell the roses. Must be working to feel right.
Time and Action
Being habitually tardy or late. No matter how important, the person seems incapable of being on time. They will often be ready early, but end up getting to their destination late.
Procrastinating. For example, having your bills habitually late even if you have the money to pay them. Putting projects off.
Indeciviness - Not being able to make a decision. No choice seems right.
In test taking multiple choice is torture because the OCD sufferer can always find an exception to the rule. For instance, if the choice is yes or no and the question is ... "Is grass green", the sufferer might think, "well in a drought it can be brown and there is a Kentucky Blue Grass".
Asking for reasurrance over and over. Included in this is "nothing they do is done right", no matter how perfectly done.
Rituals
Eating rituals - such as avoiding a certain color, food or ritual (not letting a fork touch the lips).
Abnormal preoccupation with measuring food or counting calories.
High Morals
Scrupulosity (worrying excessively that a person may have done something wrong as it pertains to their religion), such as: thinking or saying something blasphemous or worrying that they had not done a religious ritual respectfully or correctly (repent, pray etc).
Intrusive or immoral thoughts about sex or hurting someone keeps popping into their mind.
Fear of causing phyical harm to someone. For example, fear of having run someone over with a car or fear of hurting your child.
This can either be directly or directly. The OCD sufferer might fear he is going to physically hurt someone (by suffocating them) or afraid it might happen if they do not satisfy a certain compulsion (if they do not start their car 3 times, they might cause a car accident).
Fear of saying something to make someone upset.
Phobias
An exaggerated fear or aversion towards something.
Especially:
Agoraphobia - fear of open places or being around people. Often the person can not leave their home.
Anorexia Nervosa (Self starvation), an eating disorder (fear of being fat).

Conclusion
Often times an OCD sufferer will have an obsession or a compulsion and at least 80% of OCD sufferers have both.
Often the Obsessions or Compulsions can shift, exchanging an old one for a new one.
As you can see, there are many more symptoms of OCD than washing of the hands. I totally believe that the diagnosis of OCD, no matter the type, is, in fact, just an indication that the person has a thin myelin.
Instead of getting hung up on which type someone has, I suggest they nourish the nervous system and the myelin protection which covers it.
