| ACA

Anti-cardiolipin antibodies (ACA) are antibodies often directed against cardiolipin and found in several diseases, including syphilis,antiphospholipid syndrome, livedoid vasculitis, vertebrobasilar insufficiency, Behçet's syndrome,idiopathic spontaneous abortion,and systemic lupus erythematosus (SLE).They are a form of anti-mitochondrial antibody. In SLE, anti-DNA antibodies and anti-cardiolipin antibodies may be present individually or together; the two types of antibodies act independently.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

 

Concentration (ng/mL)	200	100	50	25	12.5	6.25	3.12	0
OD	1.89	1.56	1.14	0.76	0.49	0.33	0.24	0.1
Corrected OD	1.79	1.46	1.04	0.66	0.39	0.23	0.14	-

 

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Rat ACA spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Serum(n=8)	88-103	97
Plasma(n=8)	92-107	104

 

| Linearity

Samples were spiked with high concentrations of Rat ACA and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)
1 : 2	Range (%)	82-96	88-96
	Average (%)	91	93
1 : 4	Range (%)	89-103	87-110
	Average (%)	94	98
