The SARS-CoV-2 Total Antibody Spike Semi-Quantitative Test detects antibodies to the COVID-19 spike protein, indicating an adaptive immune response from recent or prior infection. Vaccinated individuals may also test positive, though results should not be used to assess immunity or protection. Doctors use this blood test to confirm past exposure, but it is not designed to diagnose active infection or predict reinfection risk.
The Women’s Vascular Inflammation & Microvascular Disease Panel evaluates hidden causes of chest pain and shortness of breath by measuring hs-CRP, Lp-PLA2 activity, MPO, galectin-3, NT-proBNP, and insulin to identify vascular inflammation, endothelial stress, and microvascular dysfunction often missed by standard heart tests.
The SARS-CoV-2 IgG Antibody Test detects IgG antibodies that develop as an immune response to a prior COVID-19 infection. A positive result confirms past exposure but does not diagnose active illness or detect immunity from vaccination. Doctors use this blood test to evaluate unexplained symptoms, confirm prior infection, and track antibody persistence, providing useful insight into a patient’s history with coronavirus infection.
The Very Long Chain Fatty Acids (VLCFA) Test measures C22:0, C24:0, C26:0 and ratios (C24/C22, C26/C22), with phytanic and pristanic acids, by GC/MS to assess peroxisomal function. Abnormal VLCFAs support evaluation of X-linked adrenoleukodystrophy and Zellweger spectrum disorders, informing diagnosis of peroxisomal and neuro-metabolic disease in the right clinical context.
