Per Walsh et al. (2000), "Laboratory evaluation of the anorectic should include a complete blood count, electrolytes, magnesium, calcium, phosphorus, urea nitrogen, creatinine, glucose, and albumin. Measuring FSH, LH, TSH and prolactin can be helpful in evaluating the cause of the amenorrhea. An electrocardiogram is especially important in patients who are bingeing and purging, and who may have metabolic abnormalities. Bone densitometry should be considered to assess severity of bone loss, especially if the results will affect the treatment."
Thus, please consider the following,
- CBC
- CMP
- Hormones (if warranted)
- Thyroid Panel
Additionally, other tests to consider are:
- Neural Zoomer if suspected PANS/PANDAS (What markers on the Neural Zoomer Plus test may indicate PANDAS or PANS?)
- Gut Zoomer to assess microbiome status and digestive output
- Micronutrient 3.0 to assess nutrient status
