SEROLOGY I POSITIVE CONTROL (SEROLOGY I CONTROL +)
RANDOX LABORATORIES LIMITED · Model SR10352 · UDI-DI 05055273216509
Description
Serology I Postive Control is intended for use with in vitro assays for determination of antibodies to Human Immunodeficiency Virus Type 1 and 2 (HIV-1/2), antibodies to Human T-Lymphotropic Virus Type 1 and 2 (HTLV-1/2), antibodies to Hepatitis C Virus (HCV), Hepatitis B Surface Antigen (HBsAg), IgG antibodies to Hepatitis B Core Antibodies (HBc) and IgG antibodies to Treponema pallidum. Serology I Positive Control is unassayed without target values and is suitable for use on many analysers. These controls must not be used as a substitute for the mandatory manufacturer’s kit controls provided with the assay. Serology I Positive Control is helpful in determining the precision of testing systems and in identifying sources of variation.
