Let’s explore “ApoB/ApoA-I ratio — lab reference”

Often calculated. Less reliable when triglycerides are markedly elevated.

90-99 above desirable; 100-119 borderline high; 120-139 high; ≥140 very high. Risk goals may be lower.

≥75 increased; ≥125 commonly treated as a risk-enhancing level. Units are not directly interchangeable with mg/dL.

≥2 suggests higher cardiovascular risk; >10 may reflect acute inflammation and should generally be repeated when well.

Age, kidney function, obesity, rhythm, and clinical setting affect interpretation.

The test method and the reason for testing affect which cutoff your clinician uses.

Advanced lipoprotein testing. Ask your clinician to use the performing laboratory classification.

Method, units, and cutoffs vary. Dr. Purser to decide whether to retain.

Adult interval. Pregnancy and pituitary disease require different interpretation.

Binding abnormalities and severe illness may affect some free-hormone assays.

Useful in selected hyperthyroid states; not a sensitive stand-alone test for hypothyroidism.

Affected by thyroid-binding globulin, pregnancy, estrogen, and medications.
