MCL Identifiers

• Patient number is a unique numerical identifier, assigned by the site for each patient. The patient number may be used only once.
• Specimen number is a unique numerical identifier assigned by the site for each specimen or specimen derivative. The specimen number may be use donly once.
• Specimen_parent_id points ot the specimen from which the derivatives are made.
• Adjacent_specimen_id is the MCL specimen_id of adjacent biospecimens cut from the same sample. There may be multiple adjacent_specimen_id values relating to one specimen_id.

Participant Identifier

To identify a patient for data submitted to the MCL data archive, you will need:

1. Your Site ID - see MCL Site IDs
2. Unique integer (3 digits) assigned to each participant

The format for the participant identifier is:

<MCL><Site ID>_<participant number>

Example:

MCL82_001  where the MCL study is indicated, Johns Hopkins = site 82, and participant = 001

For three participants from Johns Hopkins:

MCL82_001

MCL82_002

MCL82_003

Biospecimen Identifier

To identify a biospecimen associated with a participant and data submitted to the MCL data archive, you will need:

1. Participant identifier, as formatted above
2. Specimen type, where 1 = tissue, 2= blood, 3=DNA and 4=RNA (more types to be coded as needed)
3. Unique integer (four digits) assigned to each biospecimen

The format for the participant identifier is:

<MCL participant ID>_<specimen type><specimen number>

Example:

MCL82_001_10001  where the MCL study is indicated, Johns Hopkins = site 82, participant = 001, specimen type is 1 (tissue), and the unique specimen identifier is 0001.

For three biospecimens from Johns Hopkins, patient MCL82_001:

MCL82_001_10001

MCL82_001_10002

MCL82_001_10003
