Labwork and Blood Tests for Endometriosis
While several companies are working to develop one, there is no single blood test that can definitively diagnose endometriosis yet. It takes a long time to determine if a test has the reliability “so that no patients with actual endometriosis would be missed and no women without endometriosis would be selected for potentially unnecessary additional procedures” (Signorile & Baldi, 2018). Fassbender et al. (2015) notes that such tests might help receive a diagnosis more quickly so that “no women with endometriosis or other significant pelvic pathology are missed who might benefit from surgery for endometriosis associated pain and/or infertility”.
In our Diagnosis section, you can read more about some of the types of blood tests that are under investigation. Other blood tests can be used to rule out other problems and can give an indication to investigate further but are not specific to endometriosis (such as CRP and CA-125). You can also find information in the Diagnosis section about the use of ultrasounds and magnetic resonance imaging (MRI’s) in endometriosis.
“The gold standard for the diagnosis of peritoneal endometriosis has been visual inspection by laparoscopy followed by histological confirmation [7].However, the invasive nature of surgery, coupled with the lack of a laboratory biomarker for the disease, results in a mean latency of 7–11 years from onset of symptoms to definitive diagnosis. Unfortunately, the delay in diagnosis may have significant consequences in terms of disease progression. The discovery of a sufficiently sensitive and specific biomarker for the nonsurgical detection of endometriosis promises earlier diagnosis and prevention of deleterious sequelae and represents a clear research priority….The most important goal of the test is that no women with endometriosis or other significant pelvic pathology are missed who might benefit from surgery for endometriosis-associated pain and/or infertility [17–19].”

Before and after surgery- tips on preparing
We get a lot of questions about what to expect before and after surgery. On our Resources page, we have added a section on Preparing for Surgery- Pre and Post-Operative.
In the Before Surgery section, you’ll find links to topics such as:
In the After Surgery section, you’ll find topics such as:
- What to Expect in the Weeks After Skilled Excision Surgery
- Managing Expectations Pre- and Post- Op
- Pelvic Therapy Resources
Another often asked question is whether your endo is “coming back” or persisting after surgery. This is a complicated question, but this might help:

Migraines- overlap of common conditions or close tie to endo?
Both migraines and endometriosis affect a high percentage of the population. Endometriosis affects about 10-15% of the population, while migraines affect >12% of the population (Parasar, Ozcan, & Terry, 2017; Yeh, Blizzard, & Taylor, 2018). So is any association between the two just an overlap of two common conditions? Or is there something that ties the two together?
According to several studies, there is a higher prevalence of migraines in people with endometriosis. One study noted that “the risk of endometriosis was significantly higher in migrainous women” and that “women of reproductive age who suffer from migraine should be screened for endometriosis criteria” (Maitrot-Mantelet et al., 2020). Another study noted a “linear relationship exists between migraine pain severity and the odds of endometriosis” (Miller et al., 2018). One study also attempted to account for the effects of hormones on migraines and endometriosis and found evidence of a “co-morbid relationship between migraine and endometriosis, even after adjusting for the possible effects of female hormone therapies on migraine attacks” (Yang et al., 2012).

Bowel Endometriosis Surgical Management
While many individuals have bowel/gastrointestinal symptoms with endometriosis (like diarrhea, constipation, bloating, and pain with defecation), most will not have endometriosis directly on the bowel itself. (See more on bowel endometriosis here). For those that do, there are different approaches to its surgical management.
The different approaches might include shaving, excision, and resection. Studies reveal the advantages and disadvantages of the different techniques- you can read some of those studies here. Most experts express using a team approach (such as involving a colorectal surgeon), using imaging to help guide planning before surgery (with preference for MRI), and decisions based on each individual. Those with more advanced skill in working with bowel endometriosis cite low complication rates. (You can find more on the experts’ opinions in Nancy’s Nook Facebook Group in Unit 2: Surgery).
