Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Red-top tube or gel-barrier tube
To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.

The detection of LKM-1 antibodies is an aid in the diagnosis of autoimmune hepatitis, type 2 (AIH-2). LKM antibodies are markers of AIH-2 which usually begins in childhood and generally affects children younger than 18 years of age. LKM antibodies are associated with a more serious progression of the disease. The disease is most common between the ages of 2 to 14 and is more frequent in females than males (8:1). LKM-1 antibodies have been reported in up to 8% of patients with chronic HCV infection.
A negative LKM-1 result does not rule out the presence of autoimmune hepatitis type 2. LKM-1 may be detected in some patients as a result of HCV infection and may not be the result of AIH-2.
