Overview
There are no other diagnostic studies associated with [disease name].
OR
[Diagnostic study] may be helpful in the diagnosis of [disease name]. Findings suggestive of/diagnostic of [disease name] include [finding 1], [finding 2], and [finding 3].
OR
Other diagnostic studies for [disease name] include [diagnostic study 1], which demonstrates [finding 1], [finding 2], and [finding 3], and [diagnostic study 2], which demonstrates [finding 1], [finding 2], and [finding 3].
Other Diagnostic Studies
- There are no other diagnostic studies associated with [disease name].
- [Diagnostic study] may be helpful in the diagnosis of [disease name]. Findings suggestive of/diagnostic of [disease name] include:
- [Finding 1]
- [Finding 2]
- [Finding 3]
- Other diagnostic studies for lactose intolerance include:
- Lactose intolerance test: [1]
- 50 gr of oral lactose in adults ( 2 g/kg in children) is administerd and blood glucose levels are checked at 0, 60, and 120 minutes after ingestion of glucose.
- Presentation of symptoms such as bloating, diarrhea and abdominal pain and rising of blood glucose by less than 20 mg/dL (1.1 mmol/L) are diagnostic for lactose intolerance.
- This test is used less than lactose breath hydrogen test because it needs repeated measurements of blood glucose level
- False negative results:
- Diabetes
- Bacterial overgrowth
- 50 gr of oral lactose in adults ( 2 g/kg in children) is administerd and blood glucose levels are checked at 0, 60, and 120 minutes after ingestion of glucose.
- Genetic test for primary lactase deficiency [2]
- Acquired primary lactase deficiency is associated with a CC genotype at -13.9 kb and lactase persistence is related to TT genotype[3]
- Recent publications have found that the CC genotype of the DNA variant -13910 T/C upstream of the LCT gene is associated with lactase non-persistence
- Acquired primary lactase deficiency is associated with a CC genotype at -13.9 kb and lactase persistence is related to TT genotype[3]
- Lactose intolerance test: [1]
- [Finding 3]
- [Diagnostic study 2], which demonstrates:
- [Finding 1]
- [Finding 2]
- [Finding 3]
- [Diagnostic study 2], which demonstrates:
