(d) Whether the patient is an insulin-dependent diabetic (IDDM);

(e) Patient's racial extraction;

(f) Date sample was collected;

(g) Patient history of multiple gestations; and

(h) Other pertinent medical information.

(6) The multiples of the median (MOM) shall be calculated using the laboratory's own reference data for each medically applicable time during gestation.

(7) Patient reports shall include information as indicated in section (5) of this rule. Additional information shall include:

(a) Defects screened for;

(b) Risk or cutoff used for determination of abnormal results;
