Not a quantitative test, but FREE

You basically want to see if some of your bones bend/are painful when pressed

Press with about 10 lbs (4 kg) of force at the bottom of your sternum and your tibia

The following are several descriptions from the web - basically saying the same thing

Thumb Test for Vitamin D deficiency Dr. Oz video Feb 2017

Test Yourself for "D"eficiency from Hawkeshealth

  1. With your thumb, press on your sternum (breastbone).
      Is it tender or painful?
  2. Now, press on the tibia (shin bone) of both your legs.
      Are they sore or tender?

If the answer is "yes" to both of these tests then you have a 93% chance of being Vitamin D deficient.
CLICK HERE for the 93% reference - Mayo Clinic
83% of people with low back pain were vitamin D deficient
95% of people with chronic pain had the pain go away with vitamin D

Note added at VitaminDWiki:

Sternum and both tibia feeling pain when pressed probably represents vitamin D < 25 nanograms, but it may be < 20 nanograms
Have not gotten any good references (as of Nov 2011)
If painful, it is highly advised that you should add vitamin D
Consider having a loading dose to restock in days instead of 4+ months.

LiveStrong list of symptoms March 2011

Moderate pressure on the sternum or lower leg can cause bone pain, similar to the pressure point pain seen in fibromyalgia.

Dr. Holick 2002

On physical examination the application of minimum pressure with the thumb on the sternum, anterior tibia or radius and ulna will often elicit pain and discomfort, which is a helpful diagnostic sign for osteomalacia. Vitamin D deficiency

Works for Henry Lahore, admin of VitaminDWiki

Just as I started taking vitamin D I checked, and had pain in all three locations.
No pain since then in any of my bones.
Works for me!

Vitamin D (total of 1,800,000 IU) reduced shinbone tenderness, Feb 2013

Tibial Tenderness Identifies Secondary Hyperparathyroidism Responding to High Dose Vitamin D in Pakistani Women.
Endocr Pract. 2013 Feb 20:1-20.
Ali B, Butt A, Fatima A, McDonnell ME, Masud F.; Department of Medicine, Harvard Medical School, Boston, Massachusetts.

Objectives: To assess the utility of anterior tibial tenderness (ATT) measured by visual analogue score (VAS) as a clinical diagnostic tool for vitamin D deficiency in a high-risk population of Pakistani women

Methods: ATT using a VAS was assessed in 75 premenopausal women, ages 17-56 (mean 41.3) with generalized aches and pains and calcium of less than 11.0mg/dl (normal: 8-11) at a tertiary care center in Lahore, Pakistan. This was followed by administration of 1.8 million units of vitamin D3 in divided doses. ATT, vitamin D and parathyroid hormone (PTH) levels were checked before and after the injections. Correlation between ATT, vitamin D and PTH as well as change in ATT, vitamin D and (PTH) following supplementation was determined.

Results: Pre-intervention average calcium and vitamin D were 9.3mg/dl (8-10.3) and 12.1 ng/ml (1.5-32.6) respectively. 74% (53/75) of the participants had vitamin D deficiency and elevated PTH (>60).
Mean PTH was 81.6pg/ml (29.1-370).
Change in ATT correlated strongly (r=0.422, p=0.013) with change in PTH.

Following supplementation, there was significant improvement in ATT (p<0.01), and vitamin D levels (p<0.01), with a decrease in PTH levels (p<0.01).

Conclusions: Anterior tibial tenderness is a valid clinical diagnostic tool for vitamin D deficiency in South Asian women.
