AFP (Alpha Fetoprotein) Pretreatment Lab Value

Description

AFP (Alpha Fetoprotein) Pretreatment Lab Value is a nonspecific serum protein that generally is elevated in the setting of hepatocellular carcinoma (HCC). This data item pertains to the pre-treatment lab value. A protein normally produced by a fetus. Alpha fetoprotein levels are usually undetectable in the blood of healthy adult men or women (who are not pregnant). An elevated level of alpha-fetoprotein suggests the presence of either a primary liver cancer or germ cell tumor. There are 2 related data items that record information on CEA for Colon and Rectum. * 3810: AFP Pretreatment Lab Value * 3809: AFP Pretreatment Interpretation

Rationale

Data Collection Variable in AJCC. This data item was previously collected for Liver, CS SSF #3. AFP (Alpha Fetoprotein) Pretreatment Lab Value is a Registry

Additional Info

**Source documents:** clinical laboratory report (blood serum radioimmunoassay or enzyme assay (EIA)); sometimes in history and physical or clinical statement in pathology report **Normal Reference Range:** * Adult men and non-pregnant women: 0-15 ng/ml (SI: 0-15 mg/L)

Notes

**Note 1:** **Physician Statement** * Physician statement of AFP (Alpha Fetoprotein) Pretreatment Lab Value can be used to code this data item when no other information is available. **Note 2:** **Pretreatment results only** * Record the lab value of the highest AFP test result documented in the medical record prior to treatment. The lab value may be recorded in a lab report, history and physical, or clinical statement in the pathology report. **Note 3:** **Related data item** * The same laboratory test should be used to record information in the related data item 3810: AFP Pretreatment Lab Value

Coding Guidelines

**1)** Record the highest value prior to treatment in nanograms per milliliter (ng/ml) in the range 0.1 (1 ng/ml) to 9999.9 (9999 ng/ml) in the Lab Value data item. **2)** A lab value expressed in micrograms per liter (ug/L) is equivalent to the same value expressed in ng/ml. ***Examples*** **a)** AFP Lab Value 0 ng/ml - Code 0.0 **b)** AFP Lab Value 23.6 ng/ml - Code 23.6 **c)** AFP Lab Value 11,0000 - Code XXXX.,1 **d)** AFP Lab Value Test Ordered, results not in chart - Code XXXX.7 **e)** AFP Lab Value Not documented in medical record, AFP test not done, unknown if APF test done - Code XXXX.9

Default
