0 | NASK | Not asked | This information has not been sought (e.g., patient was not asked)
0 | QS | Sufficient quantity | The specific quantity is not known, but is known to be non-zero and is not specified because it makes up the bulk of the material.'Add 10mg of ingredient X, 50mg of ingredient Y, and sufficient quantity of water to 100mL.' The null flavor would be used to express the quantity of water
0 | TRC | Trace | The content is greater than zero, but too small to be quantified
0 | MSK | Masked | There is information on this item available but it has not been provided by the sender due to security, privacy or other reasons. There may be an alternate mechanism for gaining access to this information.

Its primary purpose is for those circumstances where it is necessary to inform the receiver that the information does exist without providing any detail
0 | NA | Not applicable | No proper value is applicable in this context (e.g., last menstrual period for a male)
